I am glad you liked the game! It is indeed demo-like since I am working on a bigger project (with similar weird geometry stuff), and I don't really have time to further polish this game. After all, this game was just an exploration of the bigger project from a different perspective.
Sadly, I also don't have time to write devlogs, so there isn't one. Sorry :(. Maybe someday I'll manage to write something, but no promises.
