I'm having fun with this, however I keep encountering an error where opening the inventory (see edit below) makes the game wholly unresponsive. Can't use items, can't close the inventory, can't even back out using ESC. It's not every time, but it's happened three times in less than 20 minutes. At first I thought it was an error with one of the items malfunctioning, but it's now happened with multiple different items, which makes me unsure of whether it's triggered by some failure in the item use, or if it's opening the inventory itself that does it.
EDIT: It happened on the screen confirming if I wanted to use the rope as well, so maybe anything can trigger it.
Also, in the instructions on the webpage it lists F as the fire key, but in the game itself the E key is listed next to the equipped weapon. (I've not had a chance to test F yet but I'd assume it's correct since E wasn't doing anything.)
