Pretty cool game! I found that the combination of the interesting one-direction movement concept, along with the way the puzzles kept ramping up the complexity by introducing new machines, obstacles, and general size, really hooked me to keep wanting to play more. While at first I was annoyed and frustrated with some aspects like having a teleporter maze (never been a fav for me) and the controls being a bit slippery and wonky at times, I nevertheless found myself trying hard to work out the puzzles to get to see what would come up next.
That being said, I did get a bit burned out at the end. The combination of the incredibly busy landscape, tiny characters, annoying droning sound effects for the lasers, and the levels being too large did frustrate me. One annoyance in particular I found annoying was that the camera wasn't zoomed out enough for certain levels to let me see what buttons are connected to what elements on the map (and even if it was zoomed out enough, that would unfortunately have the side effect of the tiny graphics and very busy and difficult to parse landscape/graphics becoming even more troublesome). Also, as a unrelated note, I did find the tutorial a bit annoying with the way the screens only showed a few words at a time and if I showed up in the middle, I'd need to wait the whole time for it to get back to the start so I could read it, haha.
Basically, it's a little rough and could use some polishing up, but I think it's got a good foundation in terms of interesting levels and game mechanics.
