You can cast Trasmute on ingredients too! Before using your wings, transmute any MP regen items you have. MP regen stacking will get you through the entire dungeon very easily, so stack it up. 25 MP per fight will guarantee you a heal after every fight, and extras every so often if you really need them. For the final boss on level 80, you will want as much of the strongest Bleed and Decimate on your equipment as possible, so you might want to have 2 equipment sets at the VERY end of the game, 1 with a lot of MP regen for getting through those last 10 floors then one with a ton of Bleed and Decimate for the final battle.
Extremely laggy and the lag only increases as you play. The junp key also only seems to work about third of the time, and if you jump on an enemy in certain situations (I should say FALL on an enemy because jump didn't work properly) some of your cats will often get stuck on another platform during the fight, and if the cats on the same platform as the enemies all die, that one other cat on the other platform will cause the fight to NEVER END (unless you are on the level with the ghost dog bowser thing in which case it kills you). This game is extremely buggy, laggy, NEEDS TO BE FIXED.
