Collision detection does not work very well when an object is completely inside another. The collision is detected, but there is no transfer of momentum etc. This is due to the lack of a suitable normal. The collision routines makes object resting on the ground a bit shaky. The planes reappear directly when killed.. Sound and pause mode interact badly. bug in console where one char gets lost if the line wraps. ----------(fixed)------------------- The console mode is kind of buggy. For example the game time passes very slowly, even though the game is paused. There seem to be an off-by-one error in the dirty rect handling, as seen when the score counter leaves a vertical line of pixels behind.
