well you were at the right position... to escape.. actually the game itself had a bug in the build..
the ending goings like..
when you use the screwdriver to open the board..
you get a switch to interact with.. and when you press the switch the door opens and you can escape...
the main idea was to add more puzzles so that you have to solve them being present you and past you and that become much more fun..
sorry for the bug..!!
i will rebuild the game again and there you guys might have wonderful experience...!!
any ways thanks for playing..!!
