Ok, some basic complains that are really easy to fix: Unless you really want it, search a different, better fitting font for you projects. It can make a good difference imo. Same goes for the cursor. Its little to no work and impact is rather big. The background felt too washed out imo. Some more love into that or just a starfield background from the internet could have settet a nice mood. The pcb levels were nice, both feedback and brainpower wise, except the solution immediately dissapeared, some lighting up of the correct path would have given a nice touch. Would have probably not made all of them after each other. If you have different gameplay elements anyways i would switched to give the player more variety.
