Very cool and polished game!
I like the neon visuals and the fluidity of the score and such, it feels really nice. Knockout feels REALLY strong, there were a few times I had 2000 stamina and my oponent had 9000-11000 stamina and I still won because I got a knockout (I only got like one upgrade of knockout where it cost 2000 ). On the other hand the ghost upgrade seems kinda meh? I do get the momentum somewhat but it feels really underwhelming.
I managed to reach rank 9 :]
