I've noticed an annoying bug: sometimes the dots flow around and split into separate groups, making levels impossible to solve. Multiple times I've had 99 blue dots and 1 red dot at the end of level 13, which would fail the level.
I'll be honest, the idea is great, but I didn't like the need for timing, and the crossing wires forming a web of lines that just strains the eyes for artificial difficulty. Some levels even have independent hooks that are there just to fill the screen up, without adding to the overall complexity. So as said, good concept, but the execution needs improvement.
It appears extremely hard at first, but then you realise all that matters is not having the gates just before the C4 light up. Therefore, if it's an AND gate (marked by X), OR gate (marked by +), or XOR gate (marked by U) - just cut all input wires at the same time. If it's a NOT gate (marked by -) then leave the input wire intact, trace back one logic gate, and cut the input wire to that logic gate.
For Chrome, my save file changed from the "local" folder in the appdata folder to "roaming", another folder in appdata. Just copy over your anti_idle# from the local folder to the roaming folder and you get your save back.
