Hey, thanks very much for the feedback on the game!
There is the on/off of the tractor beam, but I maybe should of made that more clear in the controls saying - Switch ON/OFF Tractor beam. But I do see what you mean. Perhaps I could make more ON/OFF switches that turn different machines on and off for different puzzles rather than just ON switches. Thanks a lot, I appreciate the feedback and also the offer for help.
I really enjoyed your game! Really fun to play and great with the theme! Nice work!
