Do the monster titles appear randomly? I see "the Elite Merc Summoner" all over the place, more common than something like "the Tough-Looking." I'd love to see rates on titles changed - make the stronger titles more rare while slaying a monster with a stronger title would yield better results, such as more gold, EXP, better equipment... Just a thought.
Graphical glitch! If you launch the fat guy straight up into the air from a cannon and he comes down with fire, he'll start walking with fire as if he's still going to the right.
Combos increase damage, not points. Damage also affects points, but will not give you more points than the monster's health. Otherwise it'd be super easy to get an S rank on "Green Snails Only" at level 150.
