Some of the solutions felt a little arbitrary while running through, with not rhyme or reason as to why certain things worked and others didn't. The game teaches you that clicking = environment changes, but later in the game, it is not always clear what (if any) effect some of the clicks were having. There is some much needed clarity in the design of this game because its easy as a player to feel confused.
Stylistcally, I really enjoyed the way the game looks and sounds. The style you were going for came through quite strongly and it lent itself well to the game you made.
