I dont know if developer read thread, but there is a big problem in the game. You dont want to kill xenocites. When you just start the game, you geting a weak xenocites that damage you each 100 point, and limit i guess is 30 xenocites. And if you kill them, they will be replaced with strongest ones. So you dont need to kill them, untill you buy xenocite autoclicker, and have a lot of enzimes. Its a good cheesing strategy, just never save and load, untill you buy xenocite autoclicker, because when you loading game, its reset all xenocites. For developers i would advice add xenocite autocklicker from very beginning, and allow it upgrade overtime, with 1/2 of player damage, or better solution is replace it with antibodies, that will float arround and hunt xenocytes down. They will upgrade overtime, and they concentration can get rise and down, for example if they too weak at the point, and hunting one xenocyte require few antybodies, or they too strong and can kill few xenocites before dying. That will add another layer of gameplay.
