Привет! :)
It's a fun little platformer about collecting batteries, which unlock a portal so you can continue to the next level. The background of your pixel art was awesome. Good job on that. :)
Also great to see a mobile version! Wish there were a browser version too, since most people love to play game jams directly in their browser. :D
The people before me already commented on the hitboxes, but nobody pointed out the exact issue with them: the collisions are way bigger than the sprite. My suggestion (for the game-feel) would be to make the hitboxes slightly smaller than the corresponding sprite. (I added a screenshot with a suggestion)
Congrats on your first Godot Wild Jam, it's a solid entry! <3
