Game tip (after finishing it): Upgrade and use Invisible Spell. Lure them in line and vanish into thin air. Sneak into distant tile and blow them up with Fire Ball. That's it!
Goblin warrior is quite suicidal. When it got blocked from you by a foe, use freeze multiple times. The blocked goblin will try speed itself (losing 1 hp everytime) again and again thus kill itself.
My Tips: 1) Dont bother to collect costumes in early stages. Run as FARTHER as you can & collect FISHES. An upgrade gets you 3 points each, while comparing and matching up equipment only do minor benefits and REALLY consume time. 2) Use upgrade points wisely. My advice is to add 3 health to the first front kitty, half health and half attack on the second front, and all attack to the last two. Put points to stigma when and only when you seriously lack stigma. 3) Now the DREAM LINE-UP: From back to front, Cragman(rocket-man) + Smuggler(han solo) + 117(halo) + Rinku (zelda). These costumes only appear in stage 4. This way you get a fat blocking tank, a healing shooter, and 2 heavy cannons - wont lose a kitty when facing final boss. 4) Other tips: the yellow mutant turtle in stage 4 can attract fishes, get that so you can collect fish with turbo efficiency. And of course, final boss has those minions from all stages who just drop costumes.
It's really time consuming if you want to max out all perks. The only possible way to speed up is using purple crystal and when facing the final boss, spare him and let him summon the 2 skeletons so you can rip off exp. Got over 50k exp points in one game.
