Here some news screens:
I tried to make background color for the first level more natural, but I am not sure about the result (I'll not change the background color in the other level, the way the background are colored make them nearly impossible to upgraded without fully redraw the background, wich is beyond my abilities)
Do you prefer the old version of the new?
I have change the line color for Usagi hair and skin because this color is also used for her boots on some sprites
I have reworked sprite of the ennemies of the first levet to make their color fit better to their anime counterpart(and to look better too for Castor and Pollux)
the use of the palette for ennemies is pretty dumb. each ennemies use bewtween 5 and Seven color from one palette, and bewteen 1 and 3 from another palette is always loaded.
if it's allows the minimum use of palette for the full game, it make that some color are loaded but not used reducing the number of color allowed to use on the sprite sometimes.
it also make the palette load 2 time the same color, giving even more limitation to the game color.
It seem pretty clear that the game was rushed because it clearly lack optimisations.
With optimisation, the game clearly would have make 2 player mode possible and more detailled background with more color
