Hello Miri,
By any chance are you still working on this game?
Hi I'm a game developer and I have played your game. One of the attributes that can be improved is the camera. As of now, having the camera follow the player produces a dizzy effect. Its best to have the camera be changed based on the player left-clicking and dragging the mouse for different angles.
Secondly, the jump feature needs to be fixed. A player is allowed up to two jumps until they just fall and there is a lot of platforming. A player should be able to jump and mid-jump afterwards x amount of times until they fall/die off-screen.
