This dinosaur is so cute! I like a lot the idea to carry the egg with us. I would even go further and not having HP points at all, so that we only had the egg to care about :)
Brambles are a bit too dark in my opinion, they look like they're part of the backgrounds.
I unfortunately went out of bounds: I went a bit to far on the right of mushrooms and the dinosaur has fallen through the ground ^^'
Anyway, it's very fun to play and the music adds a good vibe to the game: well done!
