Fun game that definitely deserves a full release. Great job! I liked the creative interpretations of the theme scattered throughout the microgames.
I thought the choice to allow objects in the game to block the cursor was clever, but it became a little frustrating on some of the games when it didn't seem to fit. For example, you can collide with the hatchlings on the protect and balance games, which felt out of place since those specific collisions didn't really add to the gameplay. That said, this is a small polish thing and I'm sure there were bigger fish to fry during development. In a future update (if you plan to update the game), it would be nice if there was a little more time to react to some of the games (the boulder and beach ball ones come to mind, specifically).
All in all, well crafted and creative. Keep making games!
