For some weird reason, the right and bottom parts of the screen are cut-off in both normal, and cinematic mode. (The .jpgs are split directly halfway through the O in "close".)
For those having trouble with Level/screen/board/challenge No. 25: don't try it in cinematic mode, the smaller windows size lets your mouse travel more in less space. This way, you don't have to overextend your hand and can move the mouse with less worry of collision.
While I am quite disappointed at how little was actually explained (Why does this place exist? Who was that shadow with arms? if shadow people are formed when somebodies body is captured, what caused the first to spawn?), as well as how terrible both endings were (They were certainly unique, though), it was still a fun experience to run through. (Just not as great as the first two.)
Actually no... Haha, I didn't think about that. You could finish the game with 0 mushrooms.
