Zombie shooting is underwhelming at best. Why should we have to unload 20 ammos when we head shoot the bastards. I understand that body shots could have little (or no) effect on them but in a proper zombie game, head shots should be rewarded by almost instant kills. You should define to wound zones : the body/legs would be worth 1-2 points and the head 5-7 points.
To increase quality of play I would suggest adding the following features :
- Be able to use either the spacebar or left-click to advance a dialog or to play the sex minigame : needing to switch from mouse to keyboard is a bit bothersome
- Increase the time and/or lower the difficulty for the sex minigame : if the player is too much focused on the game it is almost impossible to enjoy the scene itself
- Alternatively add a post-minigame sequence and maybe a cum inside/outside choice
- Adding resolution and windowed/fullscreen modes choices would be nice too, either in-game or at startup
- The left-right keys should definitely be used for strafe
