Thanks for playing.
The stats menu explaines things:
First stage when they throw a orange and you cut it, they will deal more damage. If you fail to cut the orange they deal less damage. Also stats for how many times they get stuck, how often you un-stuck them and if you use any of the consumables. (but all that wasent required for completing the game) i just made it for the curious souls that explored the game enough.
Training, if they did not get stuck too often, will make them rotate their guns faster.
Orange/blood splatter is intentional made to obscure the screen - it is suppose to be obnoxious to the player.
No waves progression other then they spawn more and more each second. After 45 seconds it will spawn big mushrooms that 100% will kill you if you do not remove the virus.
Concept was that when the virus was gone, you would go back and play the entire game, including the missing stages as a actual cute game. Just never got around to putting that much into it.
Appriciate the suggestions
