The game is good looking and fun, but the controls are quite “imprecise”, so the game is a bit difficult.
M 2 cents: I think you can add the “jump buffer” and reduce the height of the jump (or work on the camera) to boost your game!
I did add a jump buffer, maybe it's not working or the time is too short. About the camera, I just copy-pasted the code from another game I am working on, so it's still in development. Thanks for the advice!
