First of all, it's great! It really improved my game experience.
Here's a few suggestions:
-Add all the mini-bosses, ex. the sand worm (took me a long time to defeat, maybe add it in boss strategies?)
-Add shortcuts to treasure, bosses, keys, etc. on the "Maps and Treasures" tab
That's about it (because it's great! (: XD )
It's funny. I was expecting signs reading "GIVE UP ALREADY." But the ending was fun. Tasselfoot just said that you're "incredibly stubborn," without even noting that we completed it.
