One of the most fun roguelikes I have seen in the jam so far, and I put quite a bit of time into it. Combat felt fluit, and a lot of love has been put into the art, especially with minor details like the demon of sloth attaching on to you. The room switching was also a nice touch.
Some issues: When I talk to the demons to get an upgrade, if I use my mouse to advance the dialogue it chooses the upgrade instantly (probably because mouse is still down). Also I can attack the boss with magic while they are talking to me.
