The game is... fine? Maybe that is too generous. There are elements of a good game here, and there are areas where there is some great attention to detail, but the base experience is more tedious than fun.

Pros:
Changing costumes for each world is cute and a really nice touch.
When the controls work, it can feel good to speed through the levels.
Verticality is dealt with really well.
Some of the boss design is good.
There is some real charm, with a couple of the bosses in particular standing out.

Cons:
Graphics are inconsistent and flicker a great deal even on a good pc.
Frame rate is inconsistent.
Levels are vast and lose their lustre long before they end.
Hit boxes are inconsistent, and I fell through the level multiple times.
There are far too many collectibles. Having 1000 pocket watches in one level means that they are tiny and hard to parse. This with the poor hit detection makes collecting a chore.
The game is more bug than game. i.e. You get caught in the body slam animation and float around the world.
Nonsensical design: Horses on rooftops and on pillars in the middle of the ocean.
Story and lore is so glossed over that it may not even be there at all.
I've almost finished the game as of writing this and I could not tell you which one is Clive and which one is Wrench.

This game wasn't fun. It wasn't unplayable, and if it ran well it would be mediocre. But the performance issues are so bad, that unless you're the developer, I can't see someone actually enjoying this experience. Play a Hat in Time instead.

i didn't knew that you lost all your objective collectibles if you take the refrigerator so i have to backtrack all the first level, i'm not gonna do that i'm gonna ask for a refund
