For starters, this game has a very unique art style. I think it fits well with how it portrays itself as "alien-like", in the end it felt really well put together.
One important thing to note: leave brightness on default, lol. You have a flashlight, don't be a dummy like me. Later on I got stuck on a wire puzzle cause brightness was too high to realize the wires turned green when active... so, yeah.
As for gameplay, it's a mix of some exploring and of course primarily puzzle solving. The puzzles are pretty much always handled through the game's magic, which is fine because there's several types with different effects, and they nailed it with combining them together in the puzzles. As you go on, things do get harder and you may get stumped a few times. But for me, a lot of those really tough ones felt very satisfying to clear once it finally clicked. You really do need to think what are the limitations of your magic if you want to get through the game, there is a Codex that tells you how magic works but it won't be a dead giveaway as to how you clear puzzles. Except Green magic maybe. Speaking of which...
Green magic I have mixed opinions on, it's encountered very late into the game thankfully but it feels as though it wasn't handled as properly as the other magic types. In itself, it's a great concept with excellent behavior when combined with other magic, but... often times I felt that I had no choice but to look at the Codex to figure out what I was supposed to be doing, even when I knew it related to the green magic. It doesn't ruin the game, and you might figure it out on your own if you experiment enough, but for me I personally couldn't figure out a few sections with green magic in it. Not all of them though, so rest assured it won't ruin the experience.
One thing I don't want to forget is the Sprint Totem. I found it a bit odd that this item is breakable. I guess in some sections it can make sense, but other big sections that didn't have a totem it just felt like... sluggish? Mainly the Hive or whatever that area was called. Navigating the main area was pretty slow. Not terrible, just a bit slower than preferable. In the sections were it felt the totem was a necessity, it was bizarre that it would break on you still, even if it lasted longer. You couldn't "refuel" it unless it broke, or there was another one somewhere. Meaning if you were in danger and it broke... good chance you just kinda die. I guess they wanted you to preserve it for important moments, but then that ends up with some areas being a little sluggish if you take it carefully, alternatively you can do what I did and run in circles near its respawn point when I suspected it would break soon.
I should mention that there are some softlocks so you really need to be careful with some puzzles, especially ones involving Indigo magic. Don't shove the cubes into a wall... it might go through it and you won't get it back. Pretty much all of the softlocks I encountered were due to this, but that's just cause I messed up. Don't let this discourage you though, I gave this 5 stars for a reason. The checkpoints are very generous and the puzzles are fairly short so even if you do screw up like this, it doesn't take long to fix your mistake cause you can just pause and load your last checkpoint, which pretty much is always the puzzle you were just doing. There are also a couple softlocks in the newest version (v5.10 i think? Something like that.) But you can fix these by reverting to previous version in the game's Properties. If I'm remembering correctly they are investigating this.
The story is also pretty nice, assuming you bother to read the logs and stuff left around. It's a nice break from all the puzzles, to just take a moment to read them. I also like how the "thoughts" of the character(s) were also written down.
All in all, great game and well made puzzles. You'll probably enjoy it if you like puzzle games.
