Made it to the tree level, after that no matter how many times I pressed restart from checkpoint the next level wouldn't unlock after I killed everyone.
While the combat is really well made it kind of gets a little stale since there is no sound or anything to do besides get to the next level, have you thought of adding a shop or a ranking system like DMC or Ultrakill?
Can't wait for you to add sound.
Also there aren't any monster girls.
