I'd never expect someone to make a game for DS in 2021. I have to check it out!
A downloadable game
This is a game where you are trying to find your brother in an abandoned mansion.
For some reason I started working on a game content only in 6 days before jam ends, so game is unfinished and cannot be completed. But you can walk around and... look around anyway.
Use dpad to walk, press buttons twice to run.
Use touchscreen to look around.
Press hand icon on touchscreen to interact with environment.
Press Start to close the game.
Should run on Nintendo DS, DSi, and 3DS.
On a PC and Android, I recommend the melonDS emulator.
Don't use DraStic, it has some weird sound issues in the game...
