I'm having a bit of trouble with module 5c. I go to rewind time and it freezes at about 6.85 seconds and swaps from 6.85 to 6.7. Second time it has done it. I will keep trying, but I'm not sure if anyone else had this problem.
Did anyone else end up breaking the sperms tail? Once it breaks it gets really hard to control. I don't like that but the game as a whole apart from that is pretty epic. :)
I am not sure if it is my computer or your game but your mute button seems to be screwing up. I will press the mute button and then a few minutes later sound will return but the mute button will still say no sound.
