first off i enjoyed the game very much i see it having more potential in areas.
1.the missile launcher lacks kick in terms of visuals and damage i would like less missiles and more damage per ammo box that would make it more of a treat to find them. id prefer about two hits per ammo box to break it if i have a strong weapon like that. it lacks visual punch maybe some level of flash and smoke (maybe slight screen shake or something similar) and i didn't notice any splash damage but maybe i missed it. at one point i was aiming upward near a corpse i believe and the missiles were hitting the corpse instead of my target.
2. the player marker should flash or be red or something that stands out to be easier to see especially since the adrenaline will (hopefully) be flowing when things get intense, that slow down is a potential buzz kill.
3. the machine gun also lacks punch the projectiles don't seem that interesting to shoot.
I hope you dont take these criticisms too harshly i did enjoy your game. I will be back to play more and i wish you a successful launch.
