Mine was called I exist, but I played the aaagrove and it was pretty nice too xD
And as for the mechanics, I did not read the discription because I played it through the rating page. But it makes sense now. I beat most of the levels without possessing any tiles!!! I thought that was the hole idea haha. But I definitely needed the core for the later puzzles. Once again props to you guys. It's an amazing game!
