Game seems very cool actually, I like it.
The slo-mo didn't feel very impactful at all but I may have been missing something.
A suggestion I'd make is to say the name of the weapon you pick up, with a slightly hinting description. When I picked up certain things, the only indication of what hitting the trigger would do is the clip size. Even simple names like 'burst rifle' or 'charge gun' or whatnot would do wonders for people unfamiliar with guns like myself.
Also the subtle trap beats are nice and fitting, screen might be a bit too flashy and wild to tell exactly whats going on during fights, considering the amount of combat options there are.
Nice game
