Within a Deep Forest is a PC platformer developed entirely by Nicklas Nygren under the moniker of Nifflas. The game available for download for free from here
Within A Deep Forest is a game set in a post-apocalyptic world in which few survived. One who did survive however was the infamous Dr. Cliché who built a time machine to travel back in time and stop his most horrible deed yet - an underwater lab with the most powerful bomb the world has ever seen, a bomb so powerful, should it ever explode, it would freeze the whole world, killing all existing life on the planet. When the game starts, someone has activated the bomb. The bomb itself is actually the second attempt to create a bomb since the first one resulted in the creation of a ball.
Pinewood Heights is essentially the hub world for the game. From here players can select numerous balls and enter the levels.
The Haraha Mountains are the introductory plains where the character learns to control the ball. A basic tutorial level which hides a secret level.
Shinock Reign is known as the "Spider level", where players have to hit a certain number of switches to unlock a path for a spider to reach.
This level unlocks the "Iron Ball"
Ljus and Utopica
As players progress through Ljus, players will unlock Utopica. Utopica is a very stylized level with a special mechanic. The entire level is constructed by wirework, and the player has to consistently readjust their vision to land on the correct color of platform.
This level unlocks the "Yoga Ball"
The Markstone Ridgemine level is the mine cart level. Reminiscent from the Donkey Kong mine cart levels, and the infamous Battletoads hoverbike level. The shortest level ingame.
This level unlocks the "Glass Ball"
That Hover Thing
That Hover thing takes part in an alien spaceship. Navigating zero gravity and laser traps are poignant in this level.
This level unlocks the "Alien Ball"
The "Lunar moon cheese extraction factory" is a level set on the moon, however it follows the rumor that the moon is made of cheese. Mice are present in the levels, and the main obstacle are giant fans and acid pits.
This level unlocks the "Rubber Ball"
Crystal Path is a level which appears to be set in a mine. With numerous lasers and small settlements, the primary ball to be used in here is the Glass ball, as it's the only ball capable of bypassing lasers.
This level unlocks the "Pathetic Ball"
Shadowlands is similar to the early Megaman games, in which it features disappearing platforms. The objective of Shadowlands is to traverse a giant tower, so a bouncy ball is the best ball to use in here.
This level unlocks the "Cold/Freeze Ball"
To get to the future, players must use the cold ball to get in the time machine. The Future is the future where the bomb went off, and froze the world. The cold ball is the only ball to use here, as it's the only one able to withstand the temperature.
This level unlocks the "Flying Ball"
The Secret Lab is the final level ingame, where the ball "Encounters" Dr Cliché. The objective is to enter a code to disable the bomb.
The ball, can be transformed into different substances with various materials found in the landscape. In the game, the ball can be killed by hazards such as spikes, water and lava. There are also creatures who can kill the ball. Players will spawn at a warp spot upon dying.
- Iron Ball: The Iron ball is the heaviest ball in the game, and is used to break through cracked rocks and get through fans
