I... Hesitated on reviewing this game due to thinking it's an insanely novel game with things I really like, but there are 3 major flaws that just sour the experience.
Let's start with the positives:
1. The Mechanics
Generally very creative and abstract, allowing for probably thousands of dumb roundabout solutions, I ended up doing a lot of random stuff for fun and the game allows you to generally thanks to being relatively lenient on how you decide to solve puzzles.
2. The Visuals
Beautiful. The different styles you encounter throughout the game are something to behold. There's some polish missing here and there, mainly with some level transitions (most notably the lack of any when exiting a level), but nothing major.
Now for the Negatives....
1. Story kinda just sucks.
Yeah this was probably the most frustrating part. The game establishes itself as a classic dystopia torn by global warming, not inherently bad but the really predictable plot built off of it is, and the cliché ending didn't help.
2. Repetitive and lack of much challenge.
Whilst I do appreciate the do-it-your-own-way nature of the puzzles it also ends up with difficult levels being hard to make, and the hardest levels I had throughout the whole game were just because I missed a piece, and that was just frustrating. Unfortunately, this lack of challenge is paired with a repetitive game, almost every puzzles feels like it's introducing a mechanic again and again and very often it ends up with the same solution to tons of levels.
3. Short and sweet but WAY overpriced
I'm all up for short and sweet games, linelith is still one of my favourite puzzles games, difference being it lasted 2 hours but cost 3 euros, this game with only 5 hours costs 25 euros, It's pretty, sure, but a much more adequate price tag would be near the 10-15 euro mark.
In Conclusion, one of the most creative games I've seen visually and sometimes mechanically, but ruined by a price tag, repetitiveness and a generic narrative.

The first thing for people to mouth often is "autorunner??????" with 0.2 hrs of playtime, and whilst it's fair for people to be upset it isn't just more meat boy, I feel it's a bit unfair to only talk about that design decision. There's a bit to like, but a lot to complain about too. It's not just a disappointing sequel, it's pretty poorly designed gameplay wise.
Before I get there, let's go over the positives. For one, it has a great artstyle and the animations are quite smooth, I liked the small touches with idle animations and the cutscenes are very charming. For two, the warp zones were pretty cool concepts, kinda harsh sometimes, but fine. And finally, a fair few gimmicks are actually quite cool but underused (like pipes in world 3, which only appeared once). Now, let's get into why I think this is simply not a good game, nevermind a sequel.
I've tried to give this game justice, so I played through the 5 base light worlds and at least attempted every regular dark level, so here we go. First off, why the hell is this game proceduraly generated? Whenever a new save is created, the game chooses a seed and randomises most level's structures. For a endless runner precision platformer, why would you do this? Platformers should be recognised for their level design, nevermind a precise one like smb, so it being semi-random is so obviously dumb it baffles me. Second, a weird design choice was making the levels in a more traditional format, being longer but with checkpoints. There's a reason original smb used short levels, being it's a tough game, so being able to take a break between short yet quite difficult levels levels was quite nice. Worse yet, A+ levels in this game is just AWFUL, nevermind the new frame-perfect S ranks. The game shows how much time you saved from an A+ after each checkpoint, problem being, if you mess up a section, guess it's time for a full restart or find a way to die before next checkpoint since there's no restart from last checkpoint option. I had a level once where there was no way to die between checkpoints, so I had to do THE WHOLE THING without more than one mistake to A+ it. The fact dark worlds are much harder contributes a lot to the new level system's issues, speaking of, the difficulty curve is very dumb, often spiking and then dropping back to piss easy, again, doubly true for dark worlds. And lastly, the elephant in the room, it's an autorunner, but worst part, it feels like a damn mobile game. The jump and punch button are the same button (or buttons) so often you'll end screwing up thanks to a precise use of, say, a teleport.
TL;DR: Great visually, but quite lacking in gameplay. Only buy on a heavy sale if you're curious to see what it's like or for visuals.

Charming and fluid.

.........I don't want to talk about how fast I racked up hours after repentance dropped (fun fact: I got 99.8 hours on the first 2 weeks).

Wonderful short and sweet experience. No real frustrating puzzles, you'll at most be stumped for 5 mins. adequate price for chill experience. Would recommend.
