I'm at the final experiment, but it seems to be one-way. Should I have finished the buttons if I don't want to redo the whole game for the secret area?
Oh, the final experiment was good fun! And the credits were well done.For those who follow, don't worry about the game ending like that, you can go back for secrets; it seems to save in the long entry room.
When you have all of the buttons activated S5 becomes accessible
:) Looking forward to it. Not quite there yet, though. Still chewing on S2 and S4
