I've been excited to play this one for a while, just was waiting to find the time to give it, turns out it was quite short anyway! (That's not a criticism)..
I think you guys killed it for a month, you should be very proud of yourselves, and the OC and enemy designs are really nice, I could honestly see this evolving into something special, if you went in that direction.
The only thing I felt it missed was some music, maybe audio queues for attacks, I'm guessing you didn't include because you wanted the end product to be exclusively your own, and if that is the case I respect that. I feel like throwing some unlicensed music in there would have done more good than bad however.
Well done team.
