Even though the graphics are okay, the actually game is...awful.
First it makes no sense at all for lion to be in a forest, but lets set that aside for this games sake. Second, "Lion Simulator" is the worst way to describe a game like this! You have a limited time to get eight sheep or deer even though lions can last days with just one deer and just two sheep. Setting that aside as well, I bet!

How about the controls? This lion can double jump, and run endlessly, when lions can run short distances only.

You get no tutorial in game, and apparently, just running into the animal you try to catch is enough to kill them by them exploding into dozen of bloody pieces that despawn almost immediately. Also the fact that they dont run a big scary lion running towards them is not really good, but thats net-picking.

The similaritys with a real lion and this one go on and on!
Overall, this isnt worth your time because even if you do like get ten points for running down a tree, there is very little time to do the missions in, which makes you realise how obnoxious the game actually is.
Guess its just your...preference.
