The main goal is to get to the mine car. Find the steam valves to turn off the steam flowing out of pipes. Press the button on the steam valves to enable/disable steam from a particular pipe somewhere in the maze (but you’ll need to find out what pipes are being impacted). Avoid the construction worker. If he sees you, you’ll lose a life. Touch steam and you’ll lose a life. If you run out of time, you’ll lose a life, and the value of steam valves will reset.

Release notes:

Here’s a prototype build where the valve changes. It’s just a placeholder now, and no animation.

I’ll try to add some animation, and of course, make the valve have better graphics in “on” mode than just a red circle. 🙂
