It’s a decent platformer, but the controls need a lot of improvement. The horizontal movement is too sensitive and slide-y, it’s too easy to bump into spikes. It also doesn’t feel good that I can’t hold down the up key to auto jump on contact with the springs; the controls are in such a way that I have to release my left/right key, then press up, then continue pressing left/right key again, which made running and jumping simultaneously very difficult. Other improvements like collision detection and coyote time are also welcomed. Overall, I’d say this is a good attempt, keep it up! 👍
