Completely agree. There are very limited worlds and no progression at all. It's more a toy than a game. I initially planned working a lot more on it but unfortunately it didn't happen. You can always type in "hat" for a random hat that you may or not try guessing and if you're felling adventurous you could check the code for hats too.
All that said, I really appreciate you playing my game and taking your time to give me some feedback. Thank you very much!
