I don't know if there was a 48 hours limit on warmup submissions but I made this

Language used: C#
Library: Monogame

Controls:
Arrows to move
Left click to generate an explosion at mouse location
Right click to create a particle cloud

The particle cloud uses the assets > gfx > p.png file for the cloud. Large pictures may lag. It will not make particles for transparent pixels since there is no point.

The particles react to the explosions, it's pretty fun to throw them around. The explosion was hacked in really quick so the physics aren't really top notch.

Monogame should be compatible with OS X and Linux but I have never compiled Monogame for these OSes so I'm not sure how do do it. If anyone knows how, help would be appreciated!
