First off, thanks for playing the game!
Improving the shop UI to make it easier to understand is something that we iterated over a few times, and it's definitely an area the game could still be improved further.
We're thinking about rolling this into a full release, so if you'd be interested in sharing your ideas or just checking out what we're working on, feel free to come hang out with us in the Blood X Thirsty Discord!
Thanks for the great feedback!
