I have done a lot of work on the Juno First levels today. The aliens should spawn further apart (to reduce flicker) and they shouldn't appear directly in front of your ship any more (most of the time). I have also expanded the game to 16 levels, and I will be amazed if anyone can complete them all! Let me know what you think of these levels. In particular, are they too repetitive or too difficult? I haven't made any other alterations to the game yet - the changes discussed in the previous entry will be coming in the next few releases. I'm actually enjoying playing this game myself (which is rare), so I think it is coming along nicely!
