Amazing game, I found this and then constantly played it for a few days, and during that I found a few glitches. One thing is that sometimes you would be completely enclosed when you start a level, and you can't move around at all. This ended a few of my better runs, and was really annoying. I also glitched outside of the map once, no idea how, but besides all of those things, it is a great game.
On a side note, I am very confused on how to use the beast potions.
