Hello!  I'm a huge fan of Killer Queen and I more than welcome any new additions to this genre.  Few key things:
- For me I think the characters speed is too fast at the moment.  Before I can think of what to do it's already too late to react. 
- I'm not sure if it's the color palette or what but things can be hard to parse at times on screen.

Other than this love the direction you're taking!
