... two things, that bugs me are:

1) You can't access all stuff via keyboard (like equipmentmenu, ...). I would love to see the controls fully working via keyboard

2) Gameprogress will not be save (or did i miss that feature?). Since im playing it "while having a break from XYZ, i stopp playing and want to return to it later". This should be somesort of a feature

Everything else seams to be sofar working wonderul, smooth and flawless. I seriously enjoy this! (Lubuntu 20.04.x x64)

Thanks alot for this game!

Thanks for checking out the game!

Can you describe the issue you are having with the equipment menu more?  You are the first to mention it not working.  E key opens and closes it if all is working properly.

Currently the only saving that exists is the results of your runs which can be viewed by looking at the grave stones.  It occurs any time you die or exit the game via the pause menu.  As of right now you can't save while you are in the dungeon.  If it is something that gets asked for enough I will look into it in a future update, whenever I have time to dedicate to this protect.
