I've rewritten a large chunk of the collision system, and brought back in the blood particles. Here's a couple of screenshots of the blood spewed all over the place.
Shot one and two show off the pixel collision map, every tile in the game that has a collision has one of these maps. They're color coded so the particles that hit them know what direction to drip down or bounce around! I've spent a majority of today redrawing/tweaking them.
The other two are just fun bloody messes to look at!
