Good. I agree it lacked style.
That color scheme is "Vinyard" by the way and is one of the 20 or so preset color schemes. You can make/save your own under the game_setup.exe program.
I'll work on the other options you mentioned when I get time. As far as the game goes, it is important to get comfortable flying very close to shots. The biggest trick to the trade is to look for the space between shots and fly towards that. I'll probably end the game at around level 30 but for now it is infinite. The cells max out at around 129 ish. They may only spawn above that line at the bottom of the screen so even level 30000 has 129 or so cells.
Main complaints by shmup players.
-No real bullet patterns.
-No real structured levels
-Main shot is not necessary since scraping awards more points and also fires shots
-No smaller enemies
-Game becomes boring
-Player can just scrape and bomb through the game faster than playing it normally and play safe by only scraping when it is safe then bombing when the gauge is full killing all cells onscreen in 3-4 bombs
I think it may be best to add fairly simple and short levels filled with enemies and keep the main game as end level bosses. In this way I could get the non shmup player comfortable with dodging then let them take on an end level boss. This way they don't have to go into shock when the first cell goes into berserk mode since it is alone. Let them shoot down a few simple flying/shooting enemies between bosses.
Also I realize this is a demo code forum. This is not Shmup_Dev nor is it SHMUPS! Forum so I realize that any feedback is extra consideration from my friends here. I will continue to make demos, this is just something started after I failed to finish my LED demo in time. Shockwave mentioned that the site is mostly for demos so I will respect that and not always post games all over the place. This is just a remake of a very special project.

The first game after leaving Game Maker. (ewwww yes I know)
