Sadly the game seems unplayable now. After you finish a level you can't return to main menu. If you refresh the web page it record the level as beaten but you have 0 money, so you can't progress.
If someone presses reset level button after finishing the last level and before credit screen, he will be returned to the main menu without the achiemevent!
There are secrets still uncovered, who are these NPCs ? - http://prntscr.com/3use33 , and what is the little cliff in 15th dimension in the top right? Does anyone know? These NPCs are also in 15th dimension.
