Wow, this is cool! I like top-down 3d view very much. Feels fresh and smooth. Loved the tutorial and different skins on characters. The menu could be better, looking at overall quality everywhere.
This game should definitely have more players than dev and me.
The only thing I'd change is timer: it's simpler to see time left before end, and not do calculations in your head.
And I think it would really benefit from web-version to get more players
