You are a virus. You will need to collect the cheesy puffs to gain food and upgrades. Each cheesy puff you get will increase your upgrade by .5. So do not worry about upgrading. More upgrades, more damage dealt. Once you have at least 1 cheesy puff, touch the black bar to “clone” yourself. Your clones will attack, but the main one will not. The more clones you have on the screen, the more stuff it will take away. Hint at bottom. ; / Ps: cheesy puff will often go behind variables and bar. ;)
Thanks to griffpatch for the idea of a mobile friendly game. Have fun )
