Honestly a really fun game! The one big suggestion is the boss window should probably be hidden instead of destroyed, as it was causing some issues on my setup (which are like 90% my software setup's fault, as it was doing what it is supposed to do to windows and tiling them :P )
Although I couldn't figure out why Peer wanted to be in a specific place or what Bellow did at all! I also didn't hear any music, which confuses me, but oh well
