Hey there, Tiny & Big was reviewed for the Steam Deck, and we're happy to announce it's running pretty well (mostly).
The biggest hurdle is input, since this game was released way, way before Steam Input was a thing. This just means it doesn't handle Steam Deck input 100% perfectly out of the box. However, it's perfectly playable on the device with a few adjustments, and a matching input preset - each of the provided community layouts work very well! Excellent work, everyone! Additionally, there's a bug in the native Linux version that makes the menu not register any mouse button input when run on Steam Deck. We therefore advise you to instead run the Windows build inside the magic Proton emulation layer. By the time this news is posted, that should be happening automatically after you install the game. Just in case it's not, you can set it up yourself, it's easy: go to Properites, then Compatibility. Activate the checkbox which says "Force the use of a specific Steam Play compatibility tool". You can then select the latest Proton version (we tested with Proton 7.0-4). Everything else is going proper, so you should give it a whirl if you have one of those fancy devices laying around. Let us know what you think about the mobile Tiny & Big laser experience! Have fun! Black Pants
