Nice game. Small bug: After "feeding" the croc, and flipping the lever, if you click the lever again, it says "The crocodillle looks hungry", i would suggest it instead either does nothing or says: "The lever is stuck"
3/5, for a very good concept. I would think however that perhaps instead of letting each world "live" a certain amount of time, let it "live" a certain amount of "plays". So that when say 100 or maybe 400 players have played the world, let it reset.
Also please make the grey stones a tad more visible. I find they almost impossible to spot when there are 50 players jumping around it.
The Enhancements should be %tile as well. Later in the game using alot of dino's soul to "simply" get +10 vitality is a very little bonus when you allready have 400. Would be nice if it was 2% for first lvl, 4% for second level and so on. Would make it more worthwhile later in the game.
I would like to see the Happyness buildings give a small bonus each turn to happiness. ATM it seems they only give a boost when constructed/captured, and after that they are just junk, especially on the harder+ lvls. With a max foodstore of 50, its incredibly hard to use them to throw parties, making happiness a huge obstacle on the harder difficulties.
The reload takes way to long, considering its "just" an animation. Would be nice if you had a Medium, and Hard difficulty setting, where the soldiers move faster.
