So first off, this is shaping up to be a fantastic game. Unfortunately, the creator doesn't seem to be reading the itch page anymore. Anyways, there are a few problems. If you die in a pit of poison, the witch's sprite can be seen on top of the poison. You can move while the pause screen is up by transitioning rooms at the same time you bring up the pause screen (pressing up or left/right and enter at the same time).
PS. For others out there, Joellikespigs has a twitter account.
