I got stuck for a while neither finding the supermarket exit or the exit between the irregular tiles (I noticed the tiles themselves, but I tried to click on them like the entrance to the room, and apparently I never accidentally walked between them).
The pay-off of all the exploring in the template room was extremely disturbing and really good. It would have been nice to have some effects being more easy to find, just to introduce the uninitiated to the concept, but I think this is already quite impressive for a jam game. I definitely like the concept and would love to see more of this.
