I think this concept is really fun! One of the most important things about games (in my opinion) is if they are engaging. If the player is not engaged, then your message will not get across, and your game is very much engaging, so good job! It's interesting and makes me wonder how you could push the theme of "Change the Story" a bit more. I do wish dinosaurs could come back and tackle the climate crisis through combat, but I would also love to see some real-world implications! Overall very fun and promising game.
