Yeah the stairs down I just removed cos I haven't finished any content past the rat king so if you try to go down it just glitches out.
I will see if I can add useful tooltips to the stats, and work on the inventory and equips since a lot of people have mentioned it is confusing or awkward
I'll clean up the interface too. Initially I had everything in green with ascii but as I started making sprites you're right that now it looks super out of place. It might be worth me spending some time drawing a nice pixel menu for things with icons
