@delator77 I hope you are not tired waiting for my reply, I apologize for that, I'm kinda currently inactive. I thank you for your video, it's absolutely fascinating to see, how somebody else tries to complete your puzzle. As about your question, pretty much everything what you did was intended, however, at 4:00 should be completed by using R bot (That's why I used zappers there), so in this case you did beat me, congrats! Also, you can cheese this part at 1:17 mark by trapping R bot in first 5 seconds. But, since it's kinda not fair to players, I made it possible to do it without this move (just like how you did). Thanks for playing, glad, that you liked it.
