i really liked this one! The puzzles were really good. I couldn't get the undo button to work though.
Weird. What happened when you pressed the < and , key?
The < and > are on the same key on my keyboard, so I think that's what causing the issue. It works if I use the , key though.
I didn't know some keyboards were like that. I'll definitely look into things like that in the future to find work arounds. Thanks!
