The very slow movement and jump arc, and the lack of air control makes the game not feel particularly good to play.
its a great start, but you should look into platformer "game feel" for your next project
Thanks for your feedback. Yes the movement is definetly the top priority for this game. I tried to make i a little bit more realistic by adding weight to the box, but that clearly didnt work out. I would do it properly next time.
Thanks for playing!
