hey brother every level is playable and u can complete it. It needs some little bit patience and thinking. And yes quit button is not working press alt+f4 to pay respect. Hehehehe
If u rotate this u will get it..!!3 years ago(+1)
if u play first time it seems to be trial and error but u can notice that the lower u instantiate the platform the upper it will appear in the rotated version.... just my observation..
