Pros:
I like the main character and the enemies
The wallpaper/background is very pretty
Cons:
The game is very confusing, it told me to go back in level 1 and I suddenly couldn't jump anymore
It's very small too and doesn't fit in the default window, maybe size it up to 1280 x 760
Thoughts:
Maybe make it a bit more clear where to go, maybe that's just a problem with me being confused though hahah
