Bass Cave is a 2.0/2.1 Extreme Demon collaboration created and published by Bloodshot and nSwish and legitimately verified by nSwish. It is a Deadlocked-themed level originally rated as a Hard Demon but has since been buffed to an Extreme Demon and was hack-verified by Bloodshot to upload onto the servers. That version of the level was considered impossible by some players. After some time, it was updated again by nSwish to balance some of the gameplay and update the decoration. This version is the current one. It was verified legitimately by nSwish on December 5, 2019.
0-17%: Bass Cave begins with a long slow speed-mini-wave with insane timings and extremely tight spacing. The player must navigate between spikes that are just enough for the wave to pass through. In addition, there are many corridors with accurate wave spam to pass. The wave becomes normal sized for a short while and must navigate between a row of tight spikes before turning mini again and executing the same moves as before. After this wave, the player becomes a normal-sized ship, and there are extreme straight fly passages. In addition to the straight fly, the player must also navigate between green orbs and sawblades and then turning mini for a segment. After the sawblade area, the player enters a long ship-straight-fly with one block of space between the spikes. Before the song hits the drop, the player turns into a cube and must jump precisely over triple spikes and hit a pink orb on the floor. After the final triple spikes, the player turns into a wave and must hold to pass above a comedic, poorly-made Extreme Demon face. In the darkness, the player turns into a ball. They can collect the first coin by switching gravity quickly up and down before going into the text "Bass Knight".
17-40%: The player goes into a triple-speed ship segment reminiscent of Deadlocked. In addition to many gravity switch portals that the player must navigate within tiny corridors, there are also green orbs to bounce the player within turns. Memorization is key because there are insane amounts of teleportation portals. It would move the player up and down within a corridor or sometimes between two. These corridors have random spikes throughout and monsters to ensure the player must straight fly insanely well to pass this section. After a mix of ship segments with these conditions, the player turns into a ball and hits a red orb to enter a short memory segment. There are confusing orbs that the player must not hit and fake spikes on the ground that are safe to touch. In addition, there are also tight platforms the player must go in between to avoid spikes on either side. At the end of the ball segment, the player must memorize where to go as there is a corridor where there are three areas and corridors for the ball to go, but some are fake and will kill the player. After the ball, the screen fades to black, and there is a small minigame where the player must keep the arrow in the green area. Failure to do so will result in death.
40-73%: After the small minigame, the level accelerates back up to triple-speed, and the game mode switches over to a wave. The player must traverse through a bit of precise spacing, with a bit of spam involved. There is also a single gravity change in this segment. Afterward, the game mode becomes a half-speed UFO, and now the player must perform some difficult timings before the level speeds up to double-speed. Now, the player must proceed upwards while traversing through many anti-gravity portals. This UFO section ends with a pink orb. Next is a memory-based cube section. It begins with the player jumping into a yellow orb and two pink orbs that lead into a teleportation portal. After entering the teleportation portal, the player must wait a bit until hitting a green orb, a pink orb, and two blue orbs while they ignore a ton of other fake orbs in the way. Afterward, there is a difficult ship area with many downwards flying segments and teleportation portals. It ends off with an abrupt mini-portal. Then, the player's game mode switches over to a wave, and now they must travel through plenty of difficult spaces and speed portals. Then, the player enters a ball portal, and now they must time six timings before timing three more orb timings, those being two blue orbs and a green orb. The ball section concludes with four pink orbs and a green orb. The next part is an automatic cube section.
73-100%: The following part is a half-speed memory-based ship section where the player must proceed through eight pillars, all of them containing three pathways to pick from, only one of them being correct. Next to the eighth pillar, some text appears that states the word "GO!". Then, the speed accelerates up to regular speed, and the player must traverse through a UFO section containing plenty of pink orbs, many gravity portals, and a half-speed portal. Afterward, it speeds up to double-speed, and the player must proceed through a precise wave segment containing numerous tight spaces and a mini-portal. The full level ends with many mini-cube jumps with the occasional double orb timing. The cube section ends with a pink orb that leads into a black orb, somewhat similar to the ending of Prismatic Haze by Cirtrax.
The second version of the level (the original buffed version to Extreme Demon by Bloodshot) was rated, even though Bloodshot hacked that version.[1]
The update to Bass Cave that made it an Extreme Demon-worthy level was hacked, and Bloodshot confessed to this in the description of the showcase.[1]
Bloodshot's buffed version had a small typo in the level. At 16%, the player encountered a text that was supposed to say "Bass Knight". However, Bloodshot accidentally forgot the "N" in "Knight," so the level said "Bass Kight." He realized this only after the level was published. It was later fixed in the updated version by nSwish.
In December 2020, the smiling cube at the beginning of the level had a Santa hat.
File:Poorly made extreme demon face.jpgThe poorly made Extreme Demon face on a copy of the level as shown on the level editor.At 14% in the level, a very poorly made Extreme Demon face appears that became a small meme around the community. Bloodshot stated the Demon face was poorly made on purpose, as Bloodshot was streaming when making it and only included it for comedic reasons. Many players compared it to the similar Demon face at the drop in Astral Divinity, cracking ironic jokes that Bass Cave's version was "so much" better.
A few Geometry Dash Discord servers use the Demon face as a custom emoji, such as the Demonlist Public Server.
FoundMyBall even replaced the Demon face in Astral Divinity with Bass Cave's Demon Face in one of his video.
Due to its gameplay, the level is generally unfavorable to numerous players in the community.
This is npesta's least favorite level in the game.
The placement of Quantum Dynamix on May 18, 2022, knocked Bass Cave into the Legacy List of the Demonlist.
