Just remix your character trying to pass this seemingly unpassable laser. Remix Tree: https://scratch.mit.edu/projects/839849915/remixtree/ Rules: Don't remove any music, but you may add some Don't edit the background Don't edit the laser Don't remove any characters from the thumbnail. Don't make your character pass the laser (Unless your character is already metal). If your character happens to use an object to block the laser, it will immediately get destroyed. Most of all, do not cheat the laser, such as disabling it or destroying overall!
Forgive the mild laziness, but I think I finally found a way to beat this dang laser. One of the rules states that, if your character is already made of metal, it won't be affected by the laser. One of @RDash75's projects promotes the Metal Box from Mario, which turns the user to metal for a temporary amount of time. So, if you use the Metal Box, you should be safe from the laser.
