Thanks! Designing the levels was the most fun part. This was my first game (since designing little BASIC games many many years ago) so everything else was the hard part!
They were all made by hand! I had something of a method for generating them (start with an obvious path, what I wanted the first screen to look like overall, then explore the space and insert what I hoped were interesting forks and dead ends), and I wonder if that could be made procedural... Thanks!
Level 10 is the first "interesting" level (the first one which I thought required a bit of thought). I wish that were level 6, so that it could be 5 levels of tutorial/easy ones, 7 levels of interesting challenges, and then 5 levels of rule change. But that's just me.
