The art is really polished. It feels playing like a finished game. Maybe after 1 or 2 rounds, I start to get the hang of it. Great gameplay and I like the theme of the game. Maybe one improvement came to my mind, before you drop the number (and do the action), could it somehow preview how many stones/food/dinodollars would I lose (it might help at the beginning). And in some cases the text might be a bit small (if not in fullscreen), maybe you could right click on an action to zoom it.
