i love the art, but the controls were a bit hard to use as i have to constantly move the mouse to click the jump and the pause button so you could have used the keyboard for that, and your also using Input.GetMouseButtonUp instead of Input.GetMouseButtonDown.
also the start is way to short as the restart button is in the middle of the screen and the jump and pause buttons are in the bottem right.
anyways, the art was amazing and the game was really fun, it's just that the controls are a bit weird
