; # bullets do damage in all levels
; * more armor at armor-upgrade and extra armor at end of a level
; + enemies can appear at any x-position and move both left and right
; + move patterns given per enemy, not per level
; * new (faster) enemy-move system; 10 basic moves (x2 left+right)
-;
-; ! game sometimes crashes after running Nemesis:
-; (in TI-OS: screen misformed + freeze)
+; # enemies can _never_ move above or below visible screen
+; * "randomY"-enemies are placed entirely on screen (height calced)
+; # the major TI-OS crash bug WAS afterall caused by sprites drawn
+; (partially) outside screen memory. temporarily fixed by setting
+; virtual screen buffer to $8200 (enough mem there)
+; + upto 29 cool enemy sprites and redone first five levels
+; * improved enemy-move routine; smooth luring, five speeds+backwards
+; # after pause weapon will not be fired
+; # teacher key fixed (waits for GRAPH to be release before&after)
;
; + added - removed * changed # bug fixed
