I couldn't figure this out, I tried to move the pieces around and put them places, click on them under different circumstances, run them into things or eachother, but couldn't make anything connect :(
Dang it! Yeah, telegraphing what could connect to what was a challenge, and I should have spent more time making that apparent, or just made it so any block could go into any slot. It doesn't help that there are two different eye tiles. I'm sorry it wasn't more clear. Thanks for trying it out.
