So...the actual gameplay of this is pretty bad.
It claims to be rouge-lite, yet doesn't actually have any meta-game mechanics. If you are defeated, you lose everything. All your equipment, all your gold, everything. That wouldn't be so bad if you got experience or something from fighting, but you don't. You need gold to level up. And since you can't leave without an item that only drops in a specific room (that you have to fight through of course), you can't even really argue that there is an element of risk vs reward.
All of that with enemies that not only outnumber you (normal for any rpg) but also deal more damage with a single attack (they can attack multiple times) then you can heal for.
