The art is fantastic and the game feels very polished. I could easily see something like this selling on steam with a bit more content. It was a cool wholesome choose your own adventure.
My biggest feedback is that the game doesn't incentivize you to take any risks. I feel like an element that could really help the game is some kind of growing pressure that you can relieve by taking certain actions. Maybe making it so that the attack meter raises every time you go to a new zone and have more events that reduce the attack meter. One thing to remember is people will optimize the fun out of any game so the idea is to make the optimal path or the path of least resistant the most fun. If you can balance exploring to get things that will help you in fights with trying to avoid fights I think you could create a really interesting tension for the player to explore.
Also I would recommend having a dino join the party be part of the the menu options. I ended up playing several games with only Ralph because I was a fool and didnt read the hints. The dinos just looks like they belonged so much in the picture that I thought oh hey a new dino to play with before I continue on my adventure. Game started making a lot more sense once I learned I could grow the party because it was impossible to take any risks with just the one dino in the party.
The battle mechanic was pretty good though. I really liked the idea of having to balance getting hit vs hitting the opponent and leverage the different strengths of the different dinos. Like I said before if the game incentivized you or forced you into more fights I think that would be really strong.
I know I am giving criticism, but only because I see such a solid foundation here. Excellent job!
