This feels very polished. Having multiple worlds that you can switch between is really cool. The game looks very cute. I like the dragon finger as the mouse pointer and the little dragon images that pop up when clicking on the egg. The tutorials are helpful as well.
If there is a plan for a finished product, maybe adding other things in the scene to click for strategic or visual purposes would be cool. Like tap into the deck building aspect of two different nest types next to each other would give you some bonus, combined with some specific leaf hoard on the next line doubles it etc. Idk, just some thoughts that popped to my head while playing.
Good game!
