Had a lot of fun playing this demo! Exploration was enjoyable and had plenty of "ah-ha, I'm actually over here!" type reactions when finding new paths. Each new utility added a fun mechanic, and I like how several items had multiple uses.
I feel like I had almost completed it and was working on the raft challenge found just behind the starting home, when I somehow got the perfect combo of crashing the raft on the exact edge of the water and ended up immune to killboxes. Enemies could still hurt me, but water and pits had no effect.
Unfortunately when I walked through a room transition door, I became locked in place and was unable to move.
This was a lot of fun, especially since it was just a first demo. Looking forward to playing again as you continue to update it!
