Enjoyed what I played, my only real bit of feedback is we need more feedback as to what's going on. It took me a few tries to understand why certain characters were doing crap damage to certain enemies. Placement doesn't seem to be that important either, maybe adding attack ranges or abilities that allow enemy control (like pushback) would spice things up a bit.
Also some of the English is pretty bad, which makes it awkward to understand what the tutorial is saying. I'm happy to proof read any text you have :)
