Great little puzzle game. The junctions are a nice touch for a little extra challenge. It actually reminds me of a wooden train set I had as a kid! I couldn't figure out level 10 but I'll probably come back to give it another go. Nice job.
Thanks, 10 is a bit more challenging, I rushed the level design a bit, I only had a couple of hours left after fighting with the actual game mechanic far longer than I expected.
