Wow, that was super neat! I absolutely love the concept. You guys have executed the idea really well!
The only thing I personally felt was that the pathfinding of the enemies could have been improved. I really loved the glitchy enemies tho, they were fun to play against.
Another suggestion, this is a very personal opinion tho, I felt the wait time between the enemy hits below zero health and then turns glitchy can be reduced. I found myself camping an enemy until he respawned back as the glitchy version so that I could kill it again. This disrupted the otherwise quick and fast gameplay...maybe having the enemy transform immediately without a wait time is something you can try. More about how you want the game to be balanced.
Well done team, this is a super polished and fun entry! Good shit!
