Really interesting problem solving game. Could definitely be built out into a full release.
Its always tricky with abstract symbols to communicate what elements will do at a glance. If you're doing a post-jam build, I'd recommend in the initial few tutorial levels, having a partially operational solution to help players figure out what's happening. Eg. in T2, I kept trying to match colors because I wasn't thinking about electricity. But the error in T2 shows the following, which made me think the issue was on the prebuilt block rather than the issue being it not flowing past that block.
Great work!
