Wow, this really expands the game a lot. I got that retro game feeling as soon as I saw the screenshots above; then you mentioned Impossible Mission, and everything clicked into place. :D
Awesome work, can't wait to try the new features.

Initially it was going to resemble Tau Ceti unlock system much more. Almost 1:1, but I realise that Tau Ceti had limited number of rods to complete and they were not crucial for the gameplay itself (same as Impossible Mission). That's why I decided to allow to have different lengths of pieces and to split them. I am happy with how it works now - that it allows you to make the things much easier by splitting into the smallest pieces but then you get less value. I tried more variations but then it was hard to match anything. I will be trying out different sets to check if then it is easier to get larger matches.
