Getting ready for release!

Development is complete (even the installers are done), so now Blastaway only needs to go through the final (and heavy) playtest. Then, if everything turns out to be OK, the game will be released - and for free ;)

CHANGELOG

• Made doors sounds of stages 1 and 4 louder.
• Assigned the menu "back" function also to [DELETE].
• Made some internal optimizations/improvements.
• Fixed bug that caused illegal memory reads at initialization (and might crash the game).
• Fixed/improved/updated manual.
• Written installers.
