I think there is a bug on the second yellow level, 41, When hitting the edge of the window, which is the exit, the block explodes, indicating it hit an black wall. Please response!
Everytime i come back to the game i notice any improvements weren't saved. So i need to start over each time. Is it possible to remember the improvements?
Did you allow the game to save a bit of data on your computer when the warning popup came up the first time?
