What a fantastic entry. I though I'd give it a try and then got to level 73. It plays so smoothly and so fast (which is great, because if the player is doing so little between the fights, let everything happen fast - spins, shop, attacks, next).
Great stuff.
I went in blindly, without reading the description and thought to myself that this game's really cool, and then 3 elements joined into one and I was like "wha? that's awesome!".
So yeah, very solid entry, I had a blast.
As a bit of critique I have to mention mixing pixel-art characters with not-so-much-pixel-art everything else, but that's just nitpicking. Oh, and once I hit level 60 or so, I bought out everything I could, so the game was just clicking spin and watching numbers go down ;)
