Had a few requests for one of these, and it was fun to put together! You get a collection of Jack-O-Lanterns sitting atop gravestones, with a full moon and swarms of bats in the background. There's a cartoony haunted house with glowy eyes and everything. :)
The prefs on this one are a little thin on the ground currently, but I expect to add more stuff over the coming weeks. Basically, you can control the density of the bats and the color of the candles in the pumpkins, the camera speed, and can set it to only spawn bats when you touch the screen.
On the technical side, the particle system now supports animated meshes as particles, which is what the stream of bats is composed of. Particle systems now can have their spawning enabled and disabled at will, plus a few other minor features that should come in handy in the future. The visibility system worked out for Bamboo works well in this case as well. It's not nearly as object intense, but it's getting a few fps back.
I'm quite happy with how it looks overall, it was a fun project and it's cool to get it out there for folks to see!
