I had my doubts early on in the game but this game really deserves a good review. I haven't played it for long, maybe a month or so, but these regular summon events I see much more often, give really good rewards. If this is one you're on the fence on, go ahead and get in on the events/cat anniversary event giveaways and such. Also, you may find you breeze through and suddenly hit a wall, but this is really where you need to start forming good teams of cats for certain enemy types later on!
