Tridius is the gameplay as mindless as the videos make it seem :(
Well not really as mindless in my opinion. Though in order to continue the story you have to raise your Hunter Rank by doing quests though some of the them can be tricky especially two of those quests involving duel island. The main character sure has a big mouth isusing self imposed challenges there.
Basically the 2nd and final round time limit. three for the 2nd round and a minute in the final round against three enemies. I was very close to losing the round.
Now for the second self imposed rule.
1st round Three midair combo this one can be tricky if you have not mastered it.
2nd round Win in under a minute
3rd round Win without taking a single hit (Pretty easy as long as you know where the boss will land next.)
Though besides that so far the quests are quite easy. Though there are some you can do repetively which will be shown in green once you complete them.
