Very stylish, short and simple game. The presentation here is really confident, big bold solid coloured geometric shapes, bars bouncing up and down in the background in time to the beats of the music.

You play as a little shapeshifting object, when stationary - a square. If you move horizontally you turn into a circle so it looks like you're rolling, and when you jump you become a triangle that rotates to meet the ground. There is no narrative or tutorial to speak of, the game teaches you through gradually introducing and layering simple concepts throughout the handful of levels.

As a level begins, there will be little to no ambient sound and your objective is to gather a nearby little circle filled with colour. The circle will be moving erratically and emitting quiet, tinny music of some sort. Once you "pick up" the circle, you take it to a clearly marked area and the colours inside spill out and repaint your whole world. The music they contained also becomes loud and deep, and suddenly a new mechanic begins to operate in the world allowing you to progress.

The levels all proceed in broadly this way, with generous checkpoints throughout, and build up to a sort of boss battle with a novel mechanic. The punishment for death is fairly minimal and there are only four levels. I'd say it's quite achieveable to finish the game in around an hour or two.

Beating a level also unlocks a "mirror" version of that same level. As you'd expect, the whole thing is completely mirrored and the colours are also inverted. To add another wrinkle, there are no checkpoints in this mode - each mirror world must be cleared without making any mistakes. It may be just me but I found this challenge particularly gruelling, especially levels 3 and 4. There were a few bits that I just couldn't quite nail down consistently, yet the majority of the time was spent repeating the same trivial sections. Due to being rhythm-based, attempting to listen to something else while playing was a recipe for disaster. I found myself in this awkward space where the game didn't require enough to be truly engaging, but required just enough focus that if my mind wandered too much I would immediately be punished. Still, the mirror mode is really just a bonus - so it's up to you whether you want to pursue it! I found it tougher than I thought I would but eventually did managed to beat all the mirror levels.

Overall, I like this game a fair amount. It's simple, effective and a good length. A great way to spend a quiet afternoon - but think hard before considering the mirror mode as a lot of the charm wears off in repeated playthroughs!

I got this one alongside THOTH which grabbed my attention enough to get to this one asap. Am in absolute love with how relentlessly dedicated Carlsen Games is to putting pure game design before anything else, both of these games are so compact and fine-tuned that you tend to forget just how weird the game mechanics actually are.

This one's a super simple platformer, move left/right and jump and that's it, baby! The stages themselves are where things get interesting, all of them have their own set mechanics that switch around and do stuff along with the timing of the BGM.
You'll have to consider puzzles mostly in when to do what, everything basically loops around again after 1-2 bars but what's important is figuring out where in the bars you need to move/jump.
There's also a 'boss' at the end of every stage that works more as a minigame that uses a different control scheme, they're alright, the first one is kinda like a rhythm version of Buster Bros. which is cool.

I'm really excited to see what else these guys will do because this is still very much my kinda thing, cool looking shapes is eternal, babey

This is pretty much a novelty game. Play it once, get fascinated, finish it at least to some extent, and then forget it. I had my "wow" experience during the first time playing the game, and the rhythm as part of the game mechanic is quite a fun novelty, which makes for some rather interesting extensions to the standard platforming and boss fights. But now after so many years it just sits in my library and feels like a hollow memory of something that I now really want to replace with something that is much more fulfilling than this.

Certainly worth the money for such a low price, though.

Good, short, minimalistic platformer. Avoid obstacles by paying attention to the rhythm of the stages. Unlike a rhythm game where you attempt to match your movement to the sound of the game, obstacles tend to appear or shift based on that rhythm. There are also moments that are less sound based where it is your own movements that influence objects in the world. Fair design that introduces you to new kinds of obstacles or allows you to view how things work before being thrown into it. There are a few enjoyable boss fights that shift how the game plays, often being more rhythm based and involving different types of movement.

While it is short, finishing each stage does unlock a more difficult version of them.
