Wow, very impressive looking game. I ran into a couple issues though. In the second room you need to possess a host to open the door, but the directions on how to do that are in the third room. I only figured out what to do by looking at the controls in the game's description. Also, I ran into a bug where after possessing the thing that walks on walls, leaving the host caused my gravity and controls to be messed up even after possessing another host. I also think I got softlocked in the area with the big enemy that looks like a box with legs. I have access to 4 rooms, but I can't progress in 2 of them without a wall climber host, and the room with the big enemy doesn't seem to do anything.
After resetting from that softlock, I'm now seeing that in the first room, I'm supposed to go through the vent in the top right, but you can actually go through the door for some reason which is why I was confused. Apparently by going through the door, I didn't trigger a bunch of stuff like the map, title screen, and instructions. Also, I think I wasn't able to kill enemies?
I got back to where I was before I was softlocked thinking maybe the big enemy will do something now that I've hit that trigger in the beginning, but it doesn't seem to be the case. I'm kind of lost on what to next.
Game looks super impressive, I'll be sure to try it again if I could get a hint of what to do next or if it turns out the softlock is unintended and it gets fixed.
