Snake Pass is a 3D puzzle-platform game where players play as a
coral snake named Noodle with his
hummingbird sidekick named Doodle. The game has 15 levels across four themed worlds. It takes place in the fictional jungle setting of Haven Tor. The first world is themed around the jungle, the second around water, the third around lava, and the fourth around winds. Each world contains four levels, except for the final world which contains three. In each world the goal is to collect three colored gemstones called Keystones in order to reopen a portal to finish the level. In addition to the Keystones, there are 2 additional optional collectible types: Blue Whisps and gold Gatekeeper Coins. There are 20 Blue Whisps in each level, which are scattered along the critical path of the level, and five Gatekeeper Coins, which are put in more difficult-to-reach places. The game's controls are based on
snake locomotion. The player can move Noodle's head 360 degrees on a flat plane, lift it up, move Noodle forward, tighten his grip, and call Doodle to lift Noodle's tail. Moving forward in a straight line is slow, so Noodle must slither from side to side in order to gain speed. The game considers Noodle's body to be made up of many small segments, each of which is affected by physics, and so Noodle's body reacts naturally to gravity. The player must wrap Noodle's body around objects in order to stay secure and not fall, as well as to climb structures. Different worlds introduce different mechanics; in addition to bamboo structures that Noodle can wrap around to secure himself, levels can also feature bodies of water where Noodle can freely swim and dive, wind currents that can blow Noodle around, and hazards like spikes and lava pits. If Noodle is killed by a hazard or bottomless pit, he respawns at the last
checkpoint, and any collectibles he obtained after passing it are returned to their original locations. After each level is beaten, players unlock a time trial mode for
speedrunning the game. After beating the game, the player will unlock Snake Vision, a new power where the player can see all the remaining collectibles in a level while Noodle remains idle, and an arcade mode for each level in which Doodle collect fruit for points under a time limit. == Plot ==
