Hey, thank you very much for trying this out.
I'll try and get the goals not updating for web, they are working on mobile, I think there is an issue with security regarding the saving of data in a web browser and my implementation.
Your thoughts about deselecting letters and clearing to a specific point are fantastic and I'll be sure to implement them.
Yeah I've found myself clicking that button to go back to the main menu and its a hold-over to a previous version that was a very different game. I think once I use your ideas to improve the game play, I will remove that button entirely.
