Overall a good step up for Zeboyd games although it is far from perfect. Gameplay-wise it's very strong, the binary character development systems of Breath of Death and Cthulhu Saves The World have been shed and you now have an expansive ability and equipment system that let's you change up your characters on the fly. Lots of options to experiment with, and if you love burst damage playstyles then you'll love this game. One problem though is that once you get the strongest options, the short format of the battles can lead to them being a tad repetitive. This is aided by the game being short and fast paced though.
The biggest weakness ties into the previous point however, this game is very quick and unfortunately with pretty shallow writing. Consequently, this can actually make it really hard to follow what's going on as you get little room to process things, and characters are seldom developed beyond their introduction, especially painful due to the expansive cast. Tying back into gameplay, the extensive cast and line up changes forced on you make it a little undesirable to experiment with new combat options. Still, I've played far less polished independent RPG's, and by the standards of that field this is one of the better ones out there. If it was a little less derivative, I'd probably rate it just a bit higher.
