I really like the models! The player character's cool and unique, the environment's awesome! I like the big glowing mushroom and the sock!
Very smart ways to implement hints! When I first saw that red stone, it was instinctual.
It was awesome figuring out all the different reactions that the different flames had with all the objects! I didn't expect there to be, for example, a charred version of the mushrooms! Nor did I expect the resolution of the puzzle where you explode the big fruit. It all felt super creative!
Also, I have to say, the puzzle's in this game are REALLY fun. I felt like I could get really creative with how I felt the way to solve was, and a lot of times it would correct. They weren't easy puzzles, but more so very creative ones that have you experiment with different things in different ways. The knowledge you gather gets put a bit to the test with the boss, which works well and has more attacks than I expected.
The sound effects were satisfying, the ambiance noise was spot on and the boss music encapsulates a bit of the sinister context that it belongs to perfectly. Only thing I'd want to point out is to maybe sharpen the character controls a bit.
Other than that, I felt that this was well put together and I liked the puzzles a lot. Very good game!
