The good: Wonderful art style, wonderful boss design, wonderful music. Very unique and stylish - even the main menu bleeds style.
The bad: the upgrades screen does not seem to open centered at first, and never opens zoomed-out enough to see anything but the center tile properly.
The ugly: I was really hoping for some upgrade that would modify my attack options - a double-jump, a dash, a dash-swipe, anything. Most of the upgrades at present just add coins for the sake of… adding more coins?
The potential: Insanely high, actually. With more content, this has HUGE cult classic potential.
