THANK YOU so much for the support and the kind words, it really means a lot :) So glad to hear you enjoyed the game and like the concept.
Apologies to hear about the bug you ran into, I would love to be able to carry on with the concept and fix up the lingering issues and expand on the concept.
I suspected the Cash Cards might be a bit game breaking with the current setup, but I wanted to keep it that way to have it there for people discover and then find an easier way to get to all the upgrades and get the gist of the prototype a bit quicker and easier to experience all of the facets, but for a final version I would def tweak the Cash Cards a bit.
Thanks again so much for the compliments and the feedback, I truly appreciate it. Will let you know if I get to be able to carry on with this concept :)
