Welcome to my custom JSaB obstacle, the Collapsing Laser! I utilised the 'Run without screen refresh' option in My Blocks to create this! The custom attack that started it all.
Feel free to use this in your Just Shapes & Beats fan levels! Make sure to credit me for this, as this was all me. Notes You may have to spend a bit of time fiddling with the timing of it to get it to sync with your soundtrack.
