Bugs
I didn't find any
Strengths
Very funny! There's a lot of personality here and the animations compliment that well. Its a good challenge on top of that, the downward spikes on the moving platform was creative. its really entertaining and you've fleshed it out a lot with the shop and whatnot.
Weaknesses
I really couldn't think of any, great job!
Changes/Improvements
Maybe you could add a little bit to the visual style? Such as a background or something along those lines.
