Alpha 7 has now been released.
Major Features:
1. All ship engines in Vanilla have now been replaced, speeding things up a bit more. They have different visual styles, etc.
2. All Vanilla weapons now have custom FX.
Bug-Fixes:
I think that most of the remaining problems with the Missile / Thruster FX system have been fixed. Flares function properly and I hope that the last crash bugs are resolved.
To-Do:
I need to fix a couple of minor things that are bugging me that got left out of this release, mainly visual-style stuff.
There are some weapons where I'm not happy with the color / scale of their flare, etc. yet.
Haven't added in some very specific "engines" that show the player a special movement state is occurring.
I want to add in side-thrusters like I had in Vacuum, but was too busy this last week to get that done.
The new "engines" can't be damaged like Vanilla engines right now. This is a tough issue to solve without other complications.
There are probably other blemishes here and there that I'll be polishing out as this gets a little more mature as a project. I've cleaned up the OP a little, explaining what gets installed, what does what, etc.; I hope that explains how everything works a little better
