new version: ZortchBuild_1773.zip
- I made the anti-aliasing/multisampling much simpler - (it doesn't get kept turning on and off during rendering anymore - either will add some speed boost or the opposite - it was a potential culprit for the slowdowns but this change doesn't seem to have any effect)
- optimisation for particles - seems they did too many collision checks (potential cause for slowdowns?)
- a small rendering fix - now there shouldn't be artifacts anymore where two map shapes touch
- boss levels now have a background music before the fight starts
- some small map updates and fixes
