Install instructions

You can alternatively download the rom file and play it on original hardware or in a Game Boy emulator.

Since standard GB palette is B/W I suggest to go crazy and try A+DOWN palette combination when the console logo appears.

If you play on an emulator I suggest to use fancy palettes as:

Hey, Brazilian and multilingual speaker here! Currently live in Argentina (been here 5 years) and would love to help you translate and regionalize the game to my fluent languages(other than english lol): Portuguese and Spanish(am studying german, on the way to fluency, hope I can help with that someday too hehe). Feel free to email me! 


(I wouldn't mind doing it for free, I am not a professional translator but I really do love the atmosphere of the game, and love being accurate with languages ;) )

Hey scottwowlf, thank you so much for your interest, I'll contact you in private asap!

Hey finished playing the physical game on my DMG, just wanted to say excellent work very impressive. Inspired me to give GB Studio a shot 🫡

Thank you! Super happy to know that you enjoyed the game, in case you have some specific advice please feel free to add me on Discord!

Hey Mike! LOVE the game! Very space zelda and it's really fun and challenging at parts. I'm pretty much stumped at the last bit when you need to get to the space ship but there's a path you take to get to it. Im pretty stumped and wondered if there's a guide?

Hey Dustymeteor, follow the map quest indicator, or contact me in private on Discord!

How do i get virticle mode on the switch version and is this a official GB game ps i love the game

Hey pokachu, thanks for the appreciation :)
The game runs on GB but (like every GB game made in the last 20 years) it is not approved by Nintendo to run there, it is approved by them only on Nintendo Switch.
To run in vertical mode on Switch just flip the device ;) 

Hi, Mike! The game is awesome! The story is very touching. I was especially impressed by the way you managed to convey the feeling of the hero to the player. It is as if we find ourselves in the skin of the main character and feel the same as he does. So... I don't want to accidentally spoil in any way, but I read in one source that the game has several possible endings. So I want to ask, is this really true?

(English is not my native language, sorry if anything)

Hey DelPonte, you have no idea how I feel happy about what you said about the story!

Did you played the game on physical cartridge?

Yes there are alternative endings... if you do 100% on collectibles you will got different choises to do and more explanations from the final boss, and if you do 0% on the collectibles AND you never upgrade your gun and armor you have another post credit sequence... (in that case you can still collect the shield and upgrade it to make everything more simple).

No, I played the digital version.

So happy to hear that! Because at least one of the endings might break players' hearts... Actually, I've beaten the game twice. The first time I didn't collect some items, so I didn't do 100%. Then I saw information about several endings and beat the game again, this time collecting all the items, I did 100%. But somehow the ending was the same... :( Although I really got more explanation from the final boss.

Yes, final reveal from the boss is unlocked if you do 100%, also he will give you an additional choice... can't say more!

purchased a copy from Incube8.  Cannot wait to play and also to see what you have in store for the future  

Thanks for the trust! I'm already working on something  ;)

Ah man.  My copy arrived and its fantastic quality.  Good choice going with Incube8.  as for the game.  only been into the first ruin but I'm in love with it.  Art direction is fantastic.  Love the interactions between Tars and the A.I.  Mike,  you have me attention for what ever you are next working on.

Hello I'm from Brazil. Is there a possibility through a future update to get more subtitle options (at least Spanish)? At least for the digital version of the game? Because I have a Nintendo Switch and I intend to buy it for him.
Sorry for my English, I used Google Translate and congratulations on creating the game, it looks really good, I'm going to start the demo today.

¡Tu inglés es mejor que mi español!

Hola Patrick, ¡muchas gracias por tu interés en mi juego! Por el momento no tengo planes de traducirlo al español también, pero por si alguien quiere ayudarme con la adaptación en diferentes idiomas algún día lo podría hacer con mucho gusto

Thank you very much for answering. It's just that it's easier for me to understand writing in Spanish (especially if it's Latin America) in relation to Portuguese than English.
Yes and who knows in the not so distant future, it will have more languages. But I'll buy it anyway when it comes out for the Nintendo Switch. I hope it sells really well, I played the demo and I loved the game, it's really well done. All the best to you and good sales.

Tomorrow is the day! One copy coming right up to Brazil!


WoW looks really cool! Do you have Twitter account to follow your work?

Hey Rubentetro, nope TT I have only itch but please add me on Discord if you like!

Also interested in buying the full game / ROM, but it’s not here :(

Hey NielsNL, there is some delay from the distribution part, I'll do a post here as soon as 2021:ME will be available, thanks for your patience! (99.9% Q1 of 2023)

Hellooooo, When the complete digital version will be avaible ?

Hopefully before 2023 (finger crossed) the game is done 99.9999% I'm waiting for confirmation of the physical release date from the publisher to sync both  releases... Thanks you for your interest!

I really enjoyed this taster. I wish you all the best for your release!

Thank you for your feedback and for your time!

This looks amazing. I see the cart sold out. Will there be a ROM release?

Hi Eric, thanks for the interest! At the end of November we will go with the official release for both physical and digital version!

Beautiful pixel art.

Wow, this is some top notch stuff! Love it! Very well made.

Small thing I noticed. When I zap an enemy automaton, then press start to check my stats, then press start to return to the game, the zapped enemy is back there again. Is this as intended?

Hi Hohenstaufer, thank you so much for the appreciation it means a lot to me :)

Yes the respawn is totally intended, there are gameplay and narrative reasons for that! In 2021: Moon Escape I tried to create a gameplay that push the player to do ammo and life management as much as possible, sometimes kill an enemy could not be your best option... but they could spawn life recharge if they die! So you have endless life sources but limited bullet. Additionally in every moment you can teleport back to your ship from the map menu section and fully recharge ;) 

This mechanic anyway could be used to your advantage sometimes... because you can have control on the position of the enemy - I will say no more ;)

Amazing work :D 

Looks amazing! Do you have a link to buy the rom only version? Can't wait to play the full version on original hardware

Hi Ganonderp, thanks for your interest :)

The link to buy the rom version will be there in a couple of months, in the meantime you can reach me on Discord if you wish to test the full game! (its in final polishing state)

I loved this demo D1 for me

I love the art style and the 4 color thing!

Very nice work on this! Awesome!


Man this is HUUUUGE!! One of the biggest GB games released in the last decade, i cant wait to play it on cartridge.
