Obviously this is more of a personal project to help you out, but could be cool if there were more characters (rest of lowercase, uppercase, special) and the speed kept increasing. Reached level 208 with a score of 2083 before I got bored.
"Unreal Engine will no longer be free for non-gaming companies" is 100x less misleading. You are right in that technically speaking it's not misleading, but to me it feels like it's skirting the line of lying by omission. Obviously now with hindsight I can see how the "for all" changes the meaning, but it wasn't obvious (at least to me).
