Description:
Snake Cave is like the classic Snake, where you control a snake that grows longer with every piece of “food” you eat (in this game it’s called candy), but with a random generated border. The goal of this border is to make the game more dynamic and challenging. Every playthrough is different and maybe even easier/more difficult. The player can also choose between three difficulties in the options menu: Easy, Normal and Hard. Easy has a big field, slower snake and more candies. Hard has a small field, fast snake and a small amount of candies.
The game is made in Unity3D with C#.
