I found a soft lock/bug in “Over There.”
Step 1: Push ghost from spawn, suicide in the starting room
Step 2: Go right in starting room to reset room and regen the ghost
Step 3: Push the ghost into the other room with a one block sandwich without leaving the starting room.
Step 4: Suicide
You should lose all movement/get a game freeze. Also there seems to be an issue that persists even if you reset so if you complete the level the intended way, you get frozen on the flag and don’t go to the next level.
