I know it's your first game and i get that the game was designed intentionally to be hard but it's way too hard and missing a few features other platformers have and has a few bugs: when you're up agaist a wall even if you're on the ground and want to do a normal jump the game executes a walljump instead, you shouold make walljumps only possible midair. The game also has no input buffering, which is the ability to still do an action even though the player inputted that action a bit too early, for example pressing jump a few frames before hitting a platform and still jumping after touching the platform. The spikes have hitboxes that are way bigger than the spike itself, the white ropes you can climb on are invisible against the background since the tiles are white, and the spikes that pop out of the ground have no indication on where the spikes are
