The audio had me GIGGLING. The death noise took all the sting out of failing. The art on your character is very good and reads well against the background, although slightly less well when seen in front of the platforms.
The jump feels a little weird but it's acceptable for a 3-hr jam. I was expecting the platforms to be one-way pass-throughs, i.e if I jumped from below and cleared the top of them, I expected to land on the solid platform. But it did not work this way. Was that intentional?
