Thanks for playing that far! We'll be uploading a fixed build once voting is complete (with more levels as well), but if you're dying to get past it now, I'll give you some instructions.
The way the puzzle works is that by standing on one of the three small blocks, the white block (should) change color to let that robot through. Right now, it doesn't change color, but it does allow the correct robot to pass. To get past safely, follow these steps:
1. Stand on the left-most switch with the blue robot.
2. Walk through the white barrier with the red robot (do NOT touch the other switches).
3. Move the blue robot to the right-most switch.
4. Walk through the barrier with the yellow robot, and stand on the bottom switch.
5. Walk through the barrier with the blue robot.
Thanks for being patient. Hope this helps!
