It was fun finding the switches and unlocking the gates. I like that there were so many of them in a level and that they were frequent. I didn't have to look long before finding another thing to interact with. Extra points when I could press buttons in a few rooms in a single loop.
I didn't always know what I unlocked when I clicked on a switch. But sometimes I would press a few buttons and I wasn't sure what they did. It's not a big deal, but it's much nicer to see the solution in action.
