Very Unique Game. Main problem is you have to unlock story mode by playing survival mode. Story mode is fun, survival mode is not fun, So you can speed run and get USB Sticks and just die after you get 3 usb stick which unlocks 1 story mode mission, and play the story mode after and repeat this cycle.
Each story mission is unique, sometimes challenging and always rewarding, and maybe you learn something about animals if you already don't know.
If the game didn't had the mentioned problem, i would give it 5 stars as i always give 5 stars to unique games like this to pay respect to studios that don't go the easy way.
