Really nice conzept. The ingame fx are a bit too lound and I think you should add settings for audio and window mode and size. 

And for the endless mode I would like to see my score when I die. 

But other than that its fun. 

I would love it if you could add a 1v1 mode with controllers. Then I could play against my friends. 

But I love the character. Its simple but enough.
