The game looks fun, it's a classic platformer, but there's a huge problem with the controls. Sometimes I was able to make 3-4 jumps in the air, sometimes I got stuck in the walls and everything kills you even if you don't touch it... Level 3 was bad for my mental health, I didn't even touch the spikes, but they killed me (probably because of a huge collider, bigger than the size of the sprite). Anyway, it's a good start to develop the theme and add more innovation later!
