Is it possible to have a mode where your STR upgrades, gear and inventory isn't lost upon game over? Game still seems to be impossible to get past floor 3 or so because the RNG is just too brutal. You think you're doing good and suddenly get attacked by a sahagin that two-shots you because it's been enhanced by something or a mimic spawns (those should be limited to lower floors, by the way. They're a sure way to die instantly on level 1.)
Letting the player just keep their progress would slowly let them go forward.
EDIT: Also, please just remove the "There is nothing to interact with." text prompt from when you accidentally mouseclick on the ground. It's pointless and cannot be closed by any other means than a mouseclick on the window. Just frustrating and aggravating and serves no purpose.
