Thanks for playing & for the helpful feedback! Sorry about the reset 🤦. Yes - the scrolling thing is annoying - a quick fix to be able to scroll at all, and it seems to depend on mouse pointer location (has to be over the text), so it doesn't quite work properly, needed (I think) because of itch.io's iframe. Should be able to improve once I can update.
When you choose a duplicate pattern, it's actually quite strong - as you get two copies, so every time you match it (should) count double. But agree this is far from obvious.
Good idea on the entropy bar!
Thanks again!
