For the first 15 levels i thought that this game was so terrible, that i was surprised the art/models wasn't stolen, and then from level 15-25 i realized that they had in fact only made 10 different enemy/npc models
honestly the combat is very monotonous and not skill related at all, you should make side by side boards, 1 for each opponent and base it off speed/skill not waiting for 30seconds per move, and perhaps getting lucky enough to get a cascade or 5 match
