Thanks so much for checking it out! This is a great idea! I will add this to the next update (once I can publish it after judging!) haha. Yeah I have some ideas about "Stickers" for more permanent upgrades and stuff too for a few updates from now as well as adding 25 more coupons. I've been considering maybe removing the categories entirely honestly to simplify the gameloop some, but I'm still working out the details for that. haha.
Thanks so much again for the feedback!!! :D
