Has anyone played Pragmatica?

I just found it and it is pretty awesome. It's a fun and cute little game where you program robots to do tasks to complete the level.

It's actually quite difficult at times because you often have to make context dependent actions from one very limited program. It's also fun because there are basically no walkthroughs that anyone has done - probably because people think it is so hard and that some levels are impossible (they aren't. I haven't found one that is, at least) so if it seems impossible you really get to solve it on your own!

Hint: there's a command to turn on and off the robots light, and conditions for when the light is on or off. This pretty much equates to binary! It's absolutely necessary to know this for some levels but the game does not teach it to you.
