I really wanted to like this game, and I did. the art and music are wonderful.
But the goddamn fights are horribly unbalanced.
First boss? pssh, yeah, get past it immediately once you get the hang of it. The second boss and those beyond, however, is incredibly difficult, especially with how the items are randomly generated and how you're slow as hell.
The second boss is way too fast considering how randomly the items spawn. You don't get a fair opportunity to beat it and the others. This is just a dumb game of luck stuck behind a paywall.
Please work on figuring out how to decrease the difficulty of the later bosses before you charge money for this game. It's wonderful and I adore the concept and art but it's way too fucking difficult right now, chief.
