This was a great concept! I loved the tutorial! My only suggestion: There are WAY too many steps involved and the conveyer moves much too fast. Especially considering the machine takes a good second to make the neon tube, I only managed to get 1 good one shipped out.
Overall the graphics are really well done, the music spot on, and the overall execution is very good, making for an extremely polished experience! I enjoyed it, It just needs the difficulty tweaked a bit. :P
