The graphics were top-notch and the audio was great, but the gameplay was really wanting. There's not much to do except save up for new coin types that were nothing more than cosmetic and the flip counter felt sort of inconsistent and I could never tell how many flips one counted as.
Overall, the game's still pretty good, it just needs more substance to it. It didn't hold my attention much longer after I bought the bitcoin and the 4x upgrade.
