This is a well polished game! I love the cute artstyle of the game and the sound track is sooo good. I was just listening to the background music for a solid 5 minutes without playing hahaha. The idea of possessing dead bodies is cool, and it's very nice how you designed puzzles around that. For example the bat to fly, or the goblin to cut the wire powering a door. I got to the point after the scale of 18 units, and managed to open the open the door. However afterwards I think i left my body while in the poison mist and it broke the game. My character kept getting pushed upwards no matter what I did. I could move sideways, but if I try to go down my character would barely move :((. I posted a pic below of where this happened, but yeah sucks that I couldn't continue. I will give it another shot later.
Overall was still fun to play and figure out how to do the puzzles so far. Great job!
Keep up the good work.
