General tricks and glitches

Video:

Bunny Hopping - Jumping on the first frame after touching the ground to maintain your momentum. (Can be incredibly useful if combined with vectoring.) It is believed that B-Hopping on water has a 2 frame window.
Vectoring - Moving diagonaly through the air to accelerate faster than moving on the ground. You can use it to jump farther and move faster.
Celebration skip - Skipping the celebration that happens after finishing a mission. You can skip it by fulfilling the mission's requirements before activating it. It can save over 3 seconds for each mission. Not allways faster than doing it normaly.
Surface clip - Increasing Blobs size while he is between the surface of a paint pool and the floor, to clip him through the floor.
Co-op Crash - If you enter most 2D sections with Co-op active, the game crashes. We don't really know what causes this. It seems to not happen in manhole 2Ds I guess.
Music-kill Glitch - Go to the options menu in a level and then, without going back to playing, restart the level. This will make the music not play. You can fix this by going into the options menu again and then right back to playing.
Z-Pad glitch - Restarting the game while the "target button" icon from a Z-Pad is on screen, to keep it there semi-permanently
Transform Cutscene Skip (TCS) - Slamming a transform engine at the 1st possible frame, even before you truly get control of Blob, so that the cutsceene part of transform action doesn't happen. Often resulting in a softlock. For example, the ink in Hydro Station not lowering.
2.5D sections - Entering a 2D section from the 3D world. You must find a place where there is a 2D section out of bounds. You can see this by: If touching the world border softlocks you instead of respawning you. That means there is a 2D section there! - In order to enter you must be in the grounded state while touching it and then jump. (Water and slippery surfaces don't count as grounded.) After that you will be transported into the void and you may see the 2D section, and you may reach it. You will be able to move in it through 3D space! There aren't many known places to do this. These sections are also liable to Co-op Crash.
Air-brake bug - After being AFK or tabbed out of de Blob 2 for some time, you can lose the ability to air-brake. Fix it by restarting the game.
Restart offset - This isnt a glitch, but it should be known. Whenever restarting a level, the fade out animation takes up exactly 0.5 seconds. The level in turn starts playing 0.5 seconds later than normal.
Text speed differences - This also isn't a glitch, but there are differences in skipping through text in different ways. Here are 4 ways merged into one video. Holding the enter key is consistently skipping through the text on the first posssible frame, giving it an advantage over holding a button on a controller. This advantage is about 3 frames per text box. It was decided that utilising this is not against the rules.

- Launch Glitch (LG)

The biggest and perhaps most mysterious glitch. If you have it active, you can perform it by charging any object from mid-air. This will launch you either directly upward or downward. Trying again will launch you into the opposite direction as before. So a useful LG happens after every second mid-air charge.

If you don't have it active you must quit to main menu and reenter the level for a chance of getting it. Restarting normally maintains everything about LG from the game you played before, including the state of it being active and the direction it currently wants to send you.

Launch Glitch seems to have a much higher probability of appearing when you havent beaten the level yet, than if you already 100%ed it. The probability 'spreadsheet' for LG appearing in each level is here: https://docs.google.com/document/d/1ry8SbLeqkHMSWvceTKxL0y3WXGziOqD0aIUTmpeh1sQ/edit?tab=t.0

What's strange is that Launch Glitch seems to not work on ice.
