Sadly we didn't have time to add in progression to the game, however we plan to add it in future builds. The green potion increases maximum mana (and adds a bit). The way our game is related to the theme is the amnesia of the player being so out of control that they can't remember what they have been doing, and thus where they are going, causing the random room placement. (honestly, we probably stretched it a bit because we had previously had the idea for a game like this and didn't have high expectations of ourselves so we thought it'd slip under the radar)

Thanks for the feedback, as our first project we didn't expect it to be polished by the time the jam was over, and we are working on improving it, and maybe making it a little easier.

it so hard because we so mean and we so tired and we not want to have to implement progression

Being a bit more honest, we wanted the game to be fast-paced, and we just got kinda good at the game while we were playtesting, so we just kept making it harder thinking it was too easy. That, and, progression just went right over our heads.
