spacen - Day 4

Day four I started after noon with a bunch of general tweaks. I added another
sound (pain sound when hit), refined collision testing and animations. I then
listed what I still wanted to add and rethought how the mechanics should work.

Next I decided to add powerups. Reloading was already in, so I added a bullet
stack where the guy would pick them up. I stole a health pack image and drew a 
grenade, but ran out of steam before implementing them. So this was definitely 
the least productive day so far.

Three days to go so I'll need a schedule.

Thursday = finish powerups, try some ideas.
Friday = intro/menu, outro/hi-scores.
Saturday = polish, distribute.
