Thanks!
Yes! GIFfany will appear in my game in the future!
You can press "H" or "Right Click" to hide the dialogue box, then you can press again for them to reappear. (I actually forgot to mention that in the game tutorial.)
Yes, you will need to redownload the game everytime there's a new update, I've made a tutorial for the players to move their save from 0.02 to 0.03, you can check it out HERE.
(It will be the same process for the future updates while the game is in RPG Maker.)
