At this time, the area you have reached is the end of our game. The egg enemy doesn't have any interacts implemented beyond what you've already experienced. We will be posting update builds and any progress made to our new twitter account here: https://twitter.com/ThisOneStudios
Again, thank you for your feed back and playing our game!
