Absolutely LOVED the pixel art and sound effects, and the main mechanic is really cool!
Although I do think the bosses had a little too much health (I mean I beat it so I guess it wasn't that bad, just felt a bit health spongey) and some of the attacks pretty much seemed unavoidable at times.
That said this is still easily one of the best games I've played, INCREDIBLY polished and really well made! :D
Oh yeah, also how does it fit the theme? I guess the little dude is spinning?
