Progress Report, if anyone's interested, and a screenshot.
Like 20% done.
11 different enemies including the mini-boss and boss as of now.
Level 1 is finished, now working on 2.
Scoring system in place, think bonuses and chains.
Some enemies need to be redrawn, but most are satisfactory atm.
3 different type of arrays planned for now (option following player mechanics),
10 different type of absorbable weapon abilities,
explosions and effects are primitive but will be redone near the end of development.
3 Background concepts, would gladly take a few more.
Level 2:

I got a bit of inspiration from previous posters and decided to make the background so. After a while I plan to have the player dive into a never-ending tunnel for this level. More details will be added later.
(Seems like the credit list is going to be a big one, including beta testers. But there's nothing wrong with that.)
Abstract backgrounds are a bit difficult to think of, though, since I don't want to end up making something look similar to other games too much. Keep in mind that the game is located in cyberspace.
