It is a decent enough first person puzzler to recommend playing, even though I have some nitpicks to its structure.

Due to the nature of the puzzle elements, it is very easy to 'brick' yourself inside a puzzle without any indication, having to restart the whole puzzle. It's usually not a big deal, as the puzzles are pretty short, but the last puzzle of the game spans a few pretty big rooms with no checkpoints, so if you mess up with a puzzle piece, get stuck in the jumping physics or accidentally walk off the edge due to the floaty walking physics, you have to restart the whole thing again. Redoing what you just did is not a very satisfying experience.

The endings kinda follow the same pattern - you have to redo the whole game over again to see the other ending and get the achievement for them despite the only relevant choice being at the very very end. Yeah you can speedrun the game in about an hour when you know the puzzle solutions, but still, kind of annoying that you have to do that instead of just loading a checkpoint (the game deletes your save file after completion).

Still, the puzzles are novel enough and the story, while pretty predictable and not very innovative, was interesting to follow. If you like first person puzzlers, you will enjoy this game.
