Particle in quotes because I'm pretty sure there are better ways to make this happen. I'm sure full blown particle system would use some textures to great effect, but I kinda wanted to see what I could do with some triangles alone and this was the result:
Now you have an engine trails which looks pretty cool and when you destroy enemies they explode in a cloud of debris. Some larger enemies will shed debris as you hit them.
Kinda cool. Not sure what the next step is, but it was fun to get back the game for a bit and make it better. I like it. There is a beautiful simplicity with only using colored triangles as particles.
It also fits with the old-school motif that I might be going for?
