It was a favorite that my friend and I played when the PS1 came out.
You were given a monster, and you had to fight up a huge tower that had many levels on it. Each level (floor) had other monsters that you had to fight, and when you fought your monster helped you. You could get other monsters and level up your monster, and get loot on each level. It wasn't turned based or anything and it didn't have any battle scenes like final fantasy does. If you died, I'm pretty sure you had to start back at the beginning, but the levels weren't as hard since you cleared them already.
PLEASE HELP
I am going mad...
