I didn't know about corru.observer. I don't have time to really dig into that now but it was really interesting. Zachtronics is kind of how I got into all of this. I'm involved with research in educational games, and Zachtronics is basically the king of that.
That's awesome! I'm a big fan of Zachtronics games. I played TIS-100 and Shenzhen I/O over the summer break before I took the JMU class on C and Assembly, and it helped me a lot. Those two and Exapunks are definitely my favorites, although I've only actually finished the main campaign on Shenzhen I/O. Eventually I need to go back and beat Exapunks.
