This is definitely a game that is hard to forget. Its main mechanic is fun at the beginning, but it sure is infuriating as you come closer to the end of the tower, I didn't even reach floor 60 before I started to use the save glitch mentioned in some comments below, and even using the glitch I spent like 5 hours to reach to the top of the tower. 

Aside from the frustration of spending like half an hour only on level 94, I think I'll always remember the npc at level 49 (no spoiler, but I kind wanted to stay in poor man's party), or the dude at level 91 that was sick of rolling dices. 

To sum up, this is a nice game, with some amazing and funny npcs and a good atmosphere. I would recommend this game to any person that likes 8 bits games, even tho I'd understand if they never reach the finale.
