So you're redoing the entire first level from scratch?
BigBear is the large player ship.
Moonquaker is the middle white player ship.
I think that challenger is the bottom most player ship.
"Bull" is most likely the top left enemy then comes "Crown" and "Egghead"
The fourth is "Peak".
The bottom left I think is juicer, not sure.
The "Rubin" ones are the crystals seen in the demo.
The "Bunpieces" are parts of the first major enemy that devides the first level in two.
"Dubbelsol" and "Sunspot" are parts of the big suns.
"Minas" is the background rock city with a glassbulb.
"Mother" is the grey large ship that releases small ufo like ships in the demo.
"Sond" is the small mine that has a vertical red beam across the hight of the screen.
"Gellyfish" is the one that looks like one.
"Shark" is the grey ship at the beginning of the second half of the demo that realeses large bombs that explodes.
"Hat" I think is the ones that comes from the bottom up and firing in a circle in the demo.
"Probe" I think was the brown ones that comes just before the end boss of the first half.
"Semla" is the ones that the first big boss releases.
"Sentinel" is the second boss that never engages at the end of the demo.
