The Ugly:
Performance is terrible by moments, but I guess they could fix that in the long run.
The game has some very steep difficulty spikes by moments, I can understand this could be a turn down.

The Bad:
The gameplay and level design is simple, maybe too much by moments.
Enemies are very recognizable, BUT this come at the price they only have 1 design for each type you encounter. I was honestly expecting enemies to at least have a different skin per zone.
Also, the fact that you can cheese entire boss fights with the right sneakers feels cheap. I would have preferred more polished boss fights and being forced to be barefoot, so that the fight can be tailor-made to a certain skill cap.

The Good:
The art style of the game is super cool, and the overall game is a pretty blunt but enjoyable satire.

The soundtrack is absolute fire, Jaybooty is in the same boat as Mick Gordon or Jeremy Soule, just not in the same genre.
Sound design is also superb, you know what attacks you, where and when. The saturated screams of the enemies you kill, fairly stupid but funny in the given context.

Dialogues are pretty silly, but If you can embrace the silliness radiating from the game, it's an enjoyable no-brainer.

Overall a great experience, I waited this game for two years and was not disappointed.
