Yeah the feedback is appreciated. I tend to design most of my mods with the zoom mod as a requirement - just means you can get so much more in the way of interesting designs. Thanks for the feedback though and good job on the time - 7 minutes is pretty good going for EFM :-)

You are right about the practice part. Made it work in about 7 minutes, when solving it solo. I haven't used the zoom mod yet, but I also think that it shouldn't be neccessary.
I just gave feedback since I think it is a nice thing to do. What you make out of it, is totally up to you :-)

20 minutes? I think you might just need a bit more practise! I've seen it solved in under 5. Have you downloaded the zoom mod? That should help with distinguishing the symbols.

I played it and it looks nice. But it takes about 20 minutes to solve. Thats too long I think. Also Red and orange are hard to distinguish. The symbols are small so that I and J might be mixed up. Not by confusion, but by their readability.
