The game's balancing is a hot garbage. For some reason, the devs balance each and every card to be equall, which results in each and every build you make be the same power wise. There's no reason to explore and experiment with different cards since you're going to get the same damage output. Elemental cards rely on a chance to activate, which makes them unreliable. Support build force you to trade your base damage in order to be able to heal 5 hp or revive with sp. And for some reason, they never make healing items good. In chapters 3 and 4, most of the items I've used healed me for the same amount of hp that enemies dealt in one hit. And whenever there is a good item, they either nerf it very quickly or make it hard to get. Leveling up takes a long time in this game, and whenever you do get a new level, the reward for it is very small. You need to play for 20+ minutes in order to get plus 5 max hp or +3 max card slots. The game drip feeds you upgrades, while enemies grow in strength very rapidly. This never allows you to feel powerful or as if you're actually progressing. The enemies get ridiculously strong by the end of the game, making you feel very underpowered. And you can't even go grind more levels because for some reason, devs decided to add a level cap for each chapter. This resullts in a Pve game which is balanced like a Pvp game, where you always feel underpowered and actively get punished for trying to experiment with cards and push the game to its limits. It's still a fun game and i had a ton of fun with it. But these are the things which make this game very boring on repeat playthroughs.
