Game is hard to understand. Like why some upgrades last after you die but others don't? Anyway, you should add explainations next to each upgrade.

Also for the speed upgrade, I don't see how that helps...

pretty hard.

loaded fine for me. You should just spawn in the same area in my oopinon but maybe thats to easy wish you cold just hold down left mouse button to keep jumping instead of having to keep clicking.Grafics are decent and music is fine.It is kind of hars which isnt bad.

well mine loaded

Works for me but you start in more or less random places. The items don't say how much they cost until you have atleast 20 coins and if you lose all your lives you keep some of the things you bought like speed up but not small.
