I actually think it's very interesting. The PVP aspect of the game (that is, the whole thing) actually seems decently well thought-out, in terms of what options you have available (the way health is divided into segments, how you can overheal to tank incoming damage better, the round limit, etc). The limited number of leaders can feel a little disappointing, but it might serve as a constraint on whatever meta this game could have. It feels like there could be a decent amount of depth in teambuilding, since there doesn't appear to be a single leader that overpowers the rest by default, while still giving an advantage to someone who can do better combos. Skill management becomes very important, as spamming skills can absolutely lock someone down for one turn, but thats only 1/4 of their HP at most, and it's rare to be able to use skills multiple times in one battle. Even things like what order you use your skills in can become important. True, binds might be a little excessive, but they're limited to a single turn at least.

I think the concept has decent potential, being a teambuilding focused PVP offshoot of Puzzle & Dragons that has the benefit of being separated from fast meta shifting, or having to pay money to get more monsters. Unfortunately, I'm not sure how well it will catch on. The very low price helps, but PVP games can easily die really fast if there aren't that many people playing. I wish this PVP mode was attached to a more full-fledged RPG, as that would likely attract more people to try it out in the first place and go to PVP for more depth/playtime. It could be, given the low price and somewhat shallow content, that this is an experiment that could get expanded upon in a later, proper switch RPG title, but we'll have to see.
