No comment section on game page, posting here. I've tried both versions and I still get the issue of having my crosshair impaired which is highly frustrating since that means missed shots due to it not responding at all only some seconds later. I can describe it like your mouse movement being bound to your FPS and whenever it drops it (small dips say 1-3 frames will do it too) will slowdown which is the worst thing you can do in any game involving aiming. Weapon arsenal pretty balanced for the AoE(railgun penetration counts as AoE here) side and the single target ones like the uzi/machine guns seem garbage in comparison and what they lack is made up by perks which only strengthen the good weapons. Bit frustrating having your weapon be automatically replaced by what's on the ground especially if that's the only available path to peruse without taking possibly lethal damage, having a button to pick up weapons/powerups on the ground would override this issue. You seem to have prevented players to bind keys to escape but I'm still able to bind all of them to a single key, please fix this whilst also adding a keybind reset all button. As a QoL make weapon specials/ultimates different from regular weapons on the ground, add a circle to their picture or something alike.
I tend to last around up to 40k score only to then die to those aforementioned weapon pickups that are the only traversable path and succumbing to the never ending spawn of monsters that build up over 250 on screen. I don't get the point of destroying those nest/hives if the spawn number remains the same or isn't slowed down at all. You can always add a roll button with or without i-frames for the player to be able to actually kite until he gets completely overwhelmed(if that's your goal as endgame for the player) instead of relying on RNG perk choices dictating how far he's allowed to go. Overall fun, with those minor issues. Best of luck on solving this.
