About this game
In a world with four kingdoms, each colored by a season, where roles are granted by the Quadeities, strange happenings suddenly threaten the peace there. A quest begins to find each one's calling in this intrigued fate and journey through the kingdoms to get to the bottom of the mystery!
Make use of up to three roles per character to enjoy the variety in skills, effects and even costumes. In turn-based battles you can charge special orbs to use Act Over and launch up to four continuous actions. It's fun just to watch the charm of pixel arts in this fantasy JRPG!

Overall I think this is the best KEMCO RPG I've played so far (out of like 8 or so). Plot is solid, if predictable, plot. Overall a fairly typical, but competent RPG. My biggest complaint is that one of the roles (Nightmare Diver) is seemingly impossible to find. Game says it's in a particular dungeon. It's not. Internet says it's an achievement award. It's not. Since this role is needed for a quest, that also means that quest is uncompletable. Doesn't ruin the game, but it is disappointing.

I've found a minor bug in the premium shop. Here's how to reproduce it: Go to the item exchange within the shop. Select the option to buy season stones. Select the back button. The arrows used to change pages in the item exchange will be gone, preventing the switching of pages. This is a pretty minor issue. The game itelf is otherwise a pretty solid RPG. The "act-skip"/"act-over" system is pretty cool. It reminds me of the action point system in Xenogears, a favorable comparison indeed.

I loved the game a lot but I couldn't finish the story because it was just so grindy. It was already difficult at base difficulty and that was only because every boss fight practically required revives and without a defense boost would basically one shot your team one by one. For what its worth, the story was decent, I liked it, but man the boss fights were just not all that fun and were more frustrating than anything.
