It's great and funny and there no need to make it harder! But what about "Headless Zombie 3"? On Meow Beast the search engine doesn't find it, google does it but there is only the load screen with the title and no "play" button?
The game is impossible to complete on the final stage if your keyboard can't do space and left/Right at the same time.
There's a parenting glitch. When you're on a moving platform, you don't 'stick' to it and have to walk with it. (I suppose this could be intentional design, but it comes across as a glitch to me.
Game is too easy; the last level is finally a challenge, rest has little challenge to it. As it stands, the wrapper and bright colors will appeal to casuals and kids, to go for mass appeal; the level designs need to be, on average, harder.
TL;DR: Moving platform glitch. Solid effort; pretty and kid friendly. But too easy.
Very interesting game, especially liked the quest for the final 90 gear.
