So I’ve got the background scrolling nicely, I’ve got the player’s ship moving about, and I’ve added random fungi generation (currently from a pool of 7):

I’m not too sure about the design of the player’s ship though.  I might change it if I have time after everything else.  Slightly concerned also that the fungi don’t stand out enough from the background.

Next step is to add collision detection with the fungi, then fungi scanning, and spores.
