@KrinnDNZ: That's a thing I'd heard from my various playtesters as well. I wanted to strike a balance between discoverability and making things too obvious though. I wonder what I could do to make the process of discovery more fun... I had a few ideas like maybe having cues to try drawing in different areas or exposing the inner behavior graph a little more in some way (like maybe a progress indicator showing how much graph coverage has occurred) but that felt like it would ruin the feel I was going for. I'd welcome any suggestions for specific ideas to try, though!
