-; * several optimizations (init.procs some bytes smaller)
-; # enemies hit with hitpoints left disappeared (one pop too much...)
-; + bullets "charge up" (more damage) when not firing
-; - removed contrast changes
-; + more powerful bullets have different sprites (larger=more damage)

-; # screen wasn't always entirely cleared after quit
-; * waits until all keys have been released after death
-; + different bullets sizes will miss if they're too small
-; + at level start "press F1 to save"-text will be displayed
-; * w3.shiar.org displayed at title screen, black bar behind version nr

-; * bullet-icon is removed when laser is selected
-; * enemy sprite table integrated in enemy specs (-1 byte/enemy)
-; + random enemy is chosen from any number of enemies per level
-; * time to first enemy fire defined per enemy, not per level
-; + CLIPPED sprites!! no more in/out popping enemies! wow...
-; * bullets/enemies removed when _entirely_ off screen
-; # enemies would sometimes be hit by bullets going right below them
-; # size of the second bullet was too big (invisible hit)
-; * the frequency an enemy fires bullets is defined per enemy
-; + wide clipped sprites implemented (width 1-16 pixels)
-; # bosses first move left until x=100, otherwise they'd be off-screen
-; * at status bar left below ships are displayed for lives left
-; * armor bar is two pixels high (better visible)
