Thank you for taking the time to try our game!
There are no hidden mechanics; you just have to find them around the area.
You can try to interact with the outlined objects; eventually, you will realise which one is the motor for future runs (I assume you did not recognise it as a motor)!

I didn't realize "interact" was different than "open door" T_T
I played more, but got stuck on the e-mail typing task. I got the entire e-mail "green", but I didn't see a way to send it. Maybe another UI interaction I misunderstood?
Overall, though, I'm very impressed with the ambition of the game! The bugs did make it a bit hard for me to enjoy, but it was great to see so much content.
