After about ten tries to get through the chase sequence in school, I give up. Either I get caught by spirits or exploded by the fires. :(
It's tough to say something about a story if you have no idea how it finishes, but from what I saw it was a good magical girl story so far. I liked the transformation sequence for Marsha, a bit sad there wasn't one for Therese, but I assume that was due to time constraints.
I kind of wished that when you buy a spell, it gets activated immediately and removed from the shop. I can see players accidentally buying the same spell twice or forgetting to use the spells so they're activated.
The opening dungeon was very boring and frustrating. I went the opposite way at first and kept getting into battles every ten steps or so. I would have probably stopped playing if I was a normal player. I would make it either smaller or change the encounter rate.
