Great game!
There are some bug, like other mentioned before, and I also got stuck in a softlock near the end of the game, I assume, but so far I really enjoyed it.
The idea of using multiple cultist to solve puzzles is pretty cool and also how you progress in the game was well made. You unlock more and more abilities and not in a fixed order. No matter what you pick you can still solve the puzzles. Clever design!
The visuals are also appealing. It gave me a Prince of Persia vibe. The only thing that bothered me a tiny bit was that the cultists all look the same. I think some minor details, maybe different colors on a belt or something like this would help. But it was totally playable and enjoyable the way it is.
Really good work!
