I didnt explore too much, but this turned out to be a really great entry. A simple introduction in the game or 1-2 sentences on the game page would have been helpful, though.
For anyone wondering how to play: open the menu (ESC), have a glance at the help tab, and then start with buying something from the monster lottery.
Overall, the game feels pretty polished, the mood is nice (it also has some scp vibes), and the idea is strong. Solid entry!
