Neat concept, impossible controls
Decent art, and I like the idea (reminded me a bit of the Ninja Gaiden game for the DS, but with a mouse). But the fact that the mouse is used for dashing in addition to attacking is problematic: you dash constantly when you don't mean to, and sometimes dashing doesn't work properly at all. Every once in a while you do something cool on accident, and that's neat, but I feel like I have minimal control over combat. This ruins what would be an otherwise excellent package for me.
The rest of the production values on this are stellar, however, and I hope you keep on making games to improve on this model in the future.
