Just started playing the most recent update, incredibly impressive considering how far it's come in just a few months! It's pretty fun, I like the gameplay loop a lot!
The only "bug" I see right now is that your coin flip is incredibly biased towards heads. I realized this around $500 and then started just playing over and over again choosing just heads. After a few tries, I won $32k and was able to just unlock everything. Also discovered that if you purchase all the items on one tab, then go to the next and purchase more, sometimes it would forget that I purchased the previous tab's items when I return to the tab... Wasn't paying close enough attention, so sorry I don't have more specific details.
Incredible job overall! You should be proud!
