Good idea, and always fun to see Kenney assert in the wild ;)
Just one improvement I can think of, since there is already a penalty to die (going back) you could have removed the lives count and game over!

That was actually the original version of the game, but I noticed there is a voting category for "enjoyment" so I added a life system and checkpoints. The first version had the penalty of resetting back to the original spawn. I could take lives and game over out and leave check points as a system as well as an alternative option.
