Unicode isn't rendered properly, so the currency icons are just code squares. Room progress isn't saved if you exit and come back you have to start all over again from 0.
You cant really do anything after you get Studio A to level 3, because the 'try level up' button (in the help section referred to as 'try orgasm'??) goes gray even if you have enough currency for it.
The next room unlocks at level 5 but getting to this point didnt even amount to getting to level 2 so your progress is very soon stunted.
