You can actually play Grimind's alpha, containing the first level
here. I downloaded and played it, and what I thought was that the graphics weren't very good but were stylized pretty well, but the controls were a bit clunky. The puzzles so far haven't been very thought provoking or difficult, but it is only the first level so I would imagine they get harder later on. The sound design isn't the greatest, but it helps get the needed feel across regardless. The game was fairly scary at parts when you are stuck in the unknown with sounds all around the character, and the chase seen was intense. Once you get past the negatives it's actually really fun. Feels a lot like Limbo, but scarier. It definitely has potential. I'd suggest you all give it a go and see for yourself.
The english translations are also pretty horrible too btw, but they were hilarious.
