A few of the hidden achievements if you’re having trouble: The singing frog is at the lake of “Sape Oasis.” The mermaid appears in the upper left of “Buccaneer’s Den.” The SOS bottle appears in the river of “Snapvine Bridge.” The alien hunters can be found at the upper left of “Crimson Valley,” the upper right of “Snapvine Bridge,” and the upper middle of “Lost Jungle.” Dr. Walton is the monkey that appears in wave 6 of “Temple of Saqra.” Click the runes below: middle, left, right. Hope this helps.

I'm not sure if you're aware of it, so I thought I better share it: Whenever the dragon flies on "Beresad's Lair", you can click his gold. This gives you 100 gold each time. Pretty helpful.

The urge to click on every animal and every moving object, just because it *might* be killable...
4 types of shards, 4 pieces of equipped gear, feather and potions leaves 4 slots open for quest items. No room for anything else. This is a serious issue. Equipped items shouldn't take up inventory spots, neither should the spell components.
I like how they made some of the scenes almost identical to deep sleep, so then you can almost expect what is going to happen, but then at the same time, you can't.
