Click the green flag, sit back, prepare to be blown away. Press Space if you prefer to trigger the explosion yourself. Warning: loud sounds, flashing lights.
The 'fisheye' effect made it possible to animate the entire scene with a single backdrop. No sprites, no pen. Please feel free to remix! Code and backdrop by @heldlaw, April 26, 2020. Explosion sound from my game "Space Tunnel". https://scratch.mit.edu/projects/45921906/
