This was really fun, I like the presentation a lot. You end up getting pretty powerful once you grind for a little while. I also enjoyed the little sequence at the end once you kill everything.
I think a little more variation in the enemies would be good, and I think the shooting weapons could use a little love, they all felt generally the same and a little underpowered even at max level. Overall one of the better entries I've played, would love to see it developed into a full version. I've certainly spent far more time playing far inferior games.
