Thank you for reviewing my game :) Yeah, I've had multiple reports of people noticing the lack of balance, I should have spent more time on this :/
You can definitely level up your dinos to compensate. Also, you do gain new attacks as you level up, but for this prototype, they only deal more damage and have an elemental attribute associated to them (like pokemon). No fancy multi-attack or other abilities, I didn't have the time to implement them (but i wish I did) >_>
