I've finally got around to updating Fungicide. It did pretty well in the game competition and I want to see it finished to the way I imagined it.
There were plenty of comments on
https://www.syntaxbomb.com/index.php/topic,3984.0.html but I started by converting it to BlitzmaxNG which didn't require much work.
The major issue was stuttering and lagging caused by a badly coded game loop. I've re-coded it after bit of research and testing shows it to work well with lots of objects. Retrofitting it into Fungicide highlighted several other issues mainly caused by rushing to finish it for the competition deadline so I ripped out my sprite system and rewrote large parts of it including the use of SColor8 for my palette instead of the Type I used previously.
For some reason the ship moves very slowly up and down - was this on purpose?
Yes it's far too slow - quick change the speed before anybody else notices 
i would have added a way to move the ship more quickly or less quickly to be able to avoid the "spores"
This morning I finished rewriting the player controls by getting rid of the cursor left/right and replacing it with right-shift to simply reverse the direction of travel, and adding a thrust button so we can speed up (or slow down if not pressed). Being able to go faster has really changed the game dynamics. I plan to do a little more work on the controls before I am completely happy with it.
Next is the background paralax scenery!
