The basic things are working. Mouse control for a Jump&Run feels unusual, but I got Pikachu at least to level 2 \o/ You used a Game Engine for this - or is it your own engine? The collision detection isn't perfect, but with some trying I figured out how to get around it.
As others were mentioning: It feels too slow and unresponsive. And be careful with using such iconic IP. To a certain degree "fanart" might be accepted, but as I got it, you haven't created the art assets by your own?
