I died to the first boss, my party suddenly split up just before hitting the kill requirement and it was over from there.
I found the gameplay fun. The teammates wandering off was an interesting mechanic which made it more fun. Every time an ally would drift from the group I was rushing to kill the distraction and try to get them back on course. Felt like the father or babysitter trying to control a group of powerful monster killing toddlers.
The choice of sprites were good, shame you didn't have enough time to match the UI with the rest of the games aesthetic.
It was a good idea and worked well. Fantastic Job!
