You can shoot upwards and downwards now!Thanks Ohmnivore. It certainly was, although that's where the CCR connection ends, I'm afraid!
AlexHW, thanks for the feedback! I think you may well be right about the size of the HUD info; I'll be taking another look at it at some point before the end.
As for the background, it's a work in progress still, but I'm going for a bit of a weird abstract effect that I think may prove a little contentious. Hopefully it looks a little better in motion.
I've been able to ensnare my friend Anders to help out with some of the art and level design needs of the project, which is a huge boon. He's been concepting ways to improve the look of the game, and also ways to visually differentiate the first and second half, while I've been fixing odd bugs here and there.
One thing that we're keen on implementing is some sort of foreground graphical element, as seen in the video with the rocks at the bottom of the level.
This is a video of an in-progress level 1, just with generic grey blocks and no decoration. It's hard to know how much stuff to put into one levels and how quickly the challenge should ramp up, but I guess that will become more clear as we make more levels.
