+; # pointer to fifth ship corrected (ships in level 5 weren't displayed)
+; # calc doesn't crash anymore when game is continued after game over!!
+; + lives are decreased when ship is destroyed
+; # last eight pixels of divider line are shown correctly now
+;
+; 0.7.92 -- 02.IX .99 -- size 2303
+;
+; + contrast is increased one level at startup (and restored on exit)
+; + invulnerable for a sec when you enter the game (inv-pickup later)
+; + when in invulnerable-mode, your ship look different!
+; + at the beginning you get three *hitpoints* so you can be hit 3 times
+; * bottomline icons are now 16 pixels wide and 7 pixels high!
+; + hitpoint icon added: displays nr. of hps left next to a nice picture
+; * maximum invulnerability-time is increased (can last upto 1024 frames)
+; + when invulnerable-mode has nearly expired, your ship flashes!
+; * again a lot of optimizations esp. in size ('bout 100 bytes)
+; + pickups! 10% chance a destroyed enemy changes into an armor-pickup
+; # code optimization caused some bullets to reappear as "fake" bullets
+; * pickups can't be destroyed by bullets (they pass right through it)
+;
+; 0.8.93 -- 03.IX .99 -- size 2433
+;
+; + enemies move individually, not all at the same time!! Looks very nice
+; # titlescreen background is cleared (looked weird in Rascall and TI-OS)
+; + enemies fire at a ### rate instead of firing at will (too random)
+; # moving enemies don't move off the screen top/bottom (they wait there)
+; + seven playable levels going easy to hard (including moving enemies)
+; # xtraInfo data wasn't reset when a moving enemy entered the game
+; * longer delay when level is completed (NextLevel screen came too soon)
+;
+; 0.9.94 -- 04.IX .99 -- size 2693
+;
+; # pickups no longer fire bullets like normal enemies
+; + <halt>s added so the game runs slower and looks better
+; + TORPEDOES!!! Bullets that fire downwards! Just like in Nemesis
+; * a pickup selects the next icon on bottom bar instead of increasing hp
+; + an icon can be taken by pressing F2. second icon selects torpedoes
+; + first icon increases armor, icon 3 and 4 are unused for now
+; * selecting an unused icon (3+4) resets pickups like icon 1 and 2
+; * when you're destroyed, you loose one life instead of going game over
+; you also loose all upgrades and pickups, but remain in the same level
+; * random is more randomized, no more "tricks" to fool the randomizer
+; # after game over the game is terminated instead of continuing+crashing
+; - no more armor to start with. you'll have to collect them on your own
+; * of course optimizations and a few tiny bug fixes (not important)
+; * increased the size of the enemy bullets so they're better to see
