It's the best parts of Super Meat Boy an Ori and the Blind Forest all rolled into one.

Very consistent aesthetic, (which is also visually pleasing) difficult, but so rewarding when you pull off that perfect string.

Soundtrack is top notch and has already earned a spot into the just working around playlist.

And of course, if the main story isn't hard enough for you, there's always the B-Sides.

My one major complaint is that each area has a special gimmick, and you literally never see it again until the final push.I think it would have been fun to use red and blue orbs at the same time.
