It was really fun. Tried it as a ranger but got stuck at floor 300.
The problem: I had no potions left and my attacks just caused 6 damage per turn. How should i beat the endboss ?
I thing the problem was that i got the merchant girl half the floors, so at this floors i was unable to collect gold to improve my stats. The last few floor -where i definitively had needed the girl- she doesn't appear any more. As i reached the top, all portions were used. The restart option is useless at this situation, because you just start the last battle over and over again, but no way to buy new drinks.
This broke the game a bit, thats because you just get 3 stars.
ps: the ranger-attacks don't have any hint on what king of stat they relay. I guess dexterity but improving dexterity doesn't had any effect on the damage, the same with strength. So, how to improve damage ?
