Decently fun, though the upgrades don't feel influential whatsoever and are unnecessary to beat the game. The final bossfight, is pretty fun, though easily cheesable. The music occasionally stops playing, and the controls feel wonky, but overall still pretty good! I bet i would enjoy this game more if I had liked grindy games
Oh also, the graphics are stunning! Great job! (though I personally had a bit of trouble distinguishing background from foreground at first)
