Hey ! I managed to solve Laser phase very recently, but I’m not sure I did it the way you expected it haha
Anyway there are still 5 levels we don’t find ! I hope you’ll come back to Tetrobot one day and also try our levels ^^
Thank you for your answer, peace :)

Hey Boboss! This is a super late reply which I've should've done way before. To be honest I've seriously forgotten the solutions to my own puzzles... But I appreciate you two playing my Tetrobot level! I hope the both of you had some fun playing through it (even if it was months ago). Anyways, I know this might be an odd message to get after so much time, but regardless thank you for posting about it and I hope you're having a good day!

Hi Conundrum. Congratulations for your level "Laser phase" from Tetrobot. We are two people who can't find the solution at all, could we have a little hint...? :)
Peace !
