Incredibly difficult... At least, my first run of it. after going through it once or twice the levels became pretty easy. Now, I don't know if the title already had 'hard mode' on it, but I noticed after finishing it once, and it was easier than my first run. Well, p by 'pretty easy', I mean getting it down the later ones within five tries instead of twenty
Overall, good game.
Extra note: Now that I notice the other reviews and deactivated mute on the music, I quite like it. It's pretty chill, which is surprising consider what the game is about.
