This is a nice little escape room experience. I like how On Skull layers their puzzle design, and this game is definitely doing "more with less". The game is split across three levels with each level being one or two rooms in size. This constrains the puzzle design space nicely, and gives the game a real feel of an "escape room".

This game is a few hours long, which is a good length for an experience like this.

The puzzles are good combinations of codes, rather than keys, so you're not fumbling around with inventory items too much. When you do interact with items it's a question of picking it up and moving to where you need them. The item inspector is well executed. Overall the puzzles are very enjoyable.

Content warning that the final chapter does get a little creepy so be warned on that one.
