This is a very cool idea! Only thing is that I had to wait forever until the only letter I needed for a word showed up. Maybe increase the spawning probability for letters you need? :D
Yeah I agree, all letters that are in your word are all more likely to spawn. The issue is that letters that are collected arent removed from this so you could just get unlucky and get loads of wrong ones. It was something I was trying to fix but I ran out of time : /
