Thank you for the comment.
Yeah, it does get a bit tough from there.
There's partial code in there for a powerup system, shield recharge, more enemies and obstacles, and more AI interference (slow downs, speed ups, slowing your steering speed and gun failure - which is why the ship has two alternating guns). Unfortunately there wasn't going to be enough time to implement, so I spent the last bit of time on making a build that functioned around the speedup and modifying the spawn parameters, otherwise I would have missed the end of the Jam (which is also why the text alignment is wrong for messages and scores)
After the judging is complete, I will spend some time implementing the missing features and upload a new build.. probably only 5 or 6 hours to finish what I had planned.
