This game is amazing! It has a fascinating mechanical depth to it that reminds me of the Golden Sun series-- equipment and mid-battle buffs change your characters' abilities on a fundamental level-- and different enemy types really do force you to learn new approaches, since they themselves have very different strategies and you can't just power level past them. The art's simplicity is also deceptive, it's all extremely well-meshed and there's a lot more detail than you can see at first.
I'm not far enough in the story to give any opinion on the writing, which has so far been rather bare-bones and out of the way, but I hadn't seen any positive comments yet so I wanted to be sure to share. It's already the best thing I've seen to come out of RPG Maker.
