Atlas

Atlas is a demon level by Funnygame. It is well known for effects and designs that were quite innovative for late 1.8. It is generally considered a Very Easy Demon.

Gameplay
The level starts with a pretty easy cube part with a few easy timings. Then there is an easy ship part with some spikes that look like blocks. This is followed by a cube part with a bit of memorization. Then there is a relatively easy dual UFO section. This is followed by another easy dual ship part. Then there is a mostly easy double speed cube part. This is followed by a bit harder ball part that later turns into a tricky dual. Then there is an auto cube part that leads into a double speed UFO section with many crystal blocks to avoid. Then there is a relatively easy ship section with moderately tight spaces. The text Atlas appears, both regularly and flipped. This is followed by a rather difficult and tricky ball section with a bunch of memorization and weird usage of slopes. Then there is an easy ship part that starts with a few scattered blocks and spikes and later becomes a very easy slow ship with the text "Atlas by Funny Game". Then the level ends.

Trivia

 * While Another World is generally considered to be the origin of the trend of using crystals in levels, this is the actual first level that uses them.
