Cute aesthetic, good soundtrack, but the game's experience isn't quite ideal
Why not have the multiple pedrillstals charge together, instead of there being four of them for only one to charge at a time? I don't think you need all four at the same time, but having them charging on different timings would make the game more fluid. The first two bosses don't ask for it very much, as its easy to not get hit, but the final boss that actually can hit you often could use having more than one. The game has a look that makes it seem faster than it actually is, and that waiting time also makes having 0 DP be pointless, as it is easier and faster to die and restart than wait for the charge to fill and put you back to 1.
