Lovely looking game. The jumps felt good and well responding to controls. Music was a nice touch.
The fact that any edge without the grassy part is instant death is a bit much I think. There were quite a few times where I made the jump, but it still registered as touching the edge.
Perhaps making the camera move independently so if the player gets stuck they could be killed off screen would work? It would still prevent the player from essentially stopping the game by being stuck.
