haha, yeah there are definitely some completely broken coupon combinations that I added last second. haha. We have actually been working on completely restructuring the game, mainly due to some of these issues which, with the current design, are faaaar to easy to have happen. We posted a devlog yesterday about some of our ideas and how we are changing many of the coupon effects & core mechanics, but the breif gist is that categories will be "additive" only. In theory it made sense to have categories work a total down, but in practice it makes so many things too easy to break. Instead the game will be more strict to follow a "Numbers Go Up" design philosophy which will eliminate some of these at the base level. :)
We have also redesigned many of these "problematic" coupons too to not be nearly as OP in the new system. haha.
Thanks so much for playing though! I extremely appreciate this awesome breakdown! We hope that once we have more time to balance (this version was quickly put together in a month. haha), test ideas, and generally play through it it will be a MUCH more fun experience strategically. :)
Thanks so much again!!! :D
