Hey there, I watched your videos and decided to try out your game, I am writing this feedback as I play (and I am not very good at writing constructive criticism so don't take any of this as hate).
The first thing I noticed is that the sounds are very quiet, as in I turned the sound up to the max just to hear it normally.
Second, The guns feel a little light to shoot and some more meatyness and feedback would be appreciated.
Third, the box that I would get a gun from would spawn on a pillar and I would not be able to reach it.
The spawn times between waves were a little slow.
Too many flashing lights
I found that I could just run circles around the enemies and shoot at them from afar.
An aiming system, too?
Instead of removing the gun you unlocked from your UI, maybe have it read 0 since switching back and forth becomes harder when you get more guns and they keep on disappearing.
Scroll to switch between weapons.
Maybe add a sprint/ dodge mechanic.
There should be different powerups that the character could do.
Noticed that I would change a setting in the main menu and it would not save in the game.
I died so this is where my feedback ends.
So far it's actually pretty enjoyable, but like any new game it just needs a little work. Keep in mind that Cyberpunk was redevelopment for like 500 years and it still is not done.
