Can you add an option to reset data so we can play again? It's really good now, all 6 upgrades make a difference, especially with targets being harder to reach.
Option to reset data is a good way to extend playtime indeed. Your comment made me to consider prestige system. But if I won't figure out how to do it nicely soon - I'll implement upgrade data reset feature as is.
That would be even better than I hoped. By the way, I didn't want to tell you because I was having fun messing around with it but your upgrades can be upgraded past their max. Which breaks them and sets stats to zero. This is a bad thing except for the reload speed.
