Really fun! I can't help but feel like the balancing further in needs a little work though! By world 12 I'm filling quota with one click! Also- I feel like there needs to be some way to expand the number of toppings on your sandwich. Once I filled it with something I was halfway happy with, I stopped looking at the toppings bar in the shop entirely because I didn't want to mess up my synergy. Maybe add some way to upgrade toppings? Idk. One more thing, the 'choose your enemy' screen seems kind of pointless. It doesn't really matter which option I choose when they're mechanically identical.
All that said, a decent use of 45 minutes!
Great job
