After many requests, reviews and finally a really wholesome review from CompassUniverse I added a feature that I was afraid to add because I am a noob programmer sometimes :)
Finally main story (+DLC soon) levels can have multiple answers when it's possible. So some common errors like typing MOON and the solution was THE MOON now works both ways.
Thank you everyone for your feedback. The 2-3 minutes that you take to write down your experience and what you think will make the game better is something that it means the world to me.
