I think this game has a lot of potential. The controls feel pretty good, and hit boxes are generally clean.

Some of the problems I saw with the game; the music loop is too short, and the constant symbol clashing gets old really fast. The game also feels a little bit too easy, but also impossible if you decide to play for any amount of time. I got over 6k hp, but could never get enough money to actually escape with the quantity of items I had at that point. 

It's kind of minor, but the item pickups are very small, I couldn't make out what they were.

You can continually loop to the third floor and grab all the items. Maybe add a cost to go there?
