Oh if that's all it is I can do some very simple art, or even make it extra small so you can scale it up and it looks pixelated on purpose. All retro like. Just two or three colors.
Oh and I immediately fired a bomb of the left edge by accident and got an "array out of bounds" error.
EDIT: It does fire shots, looks good to me...
I'm not sure about the color palette. But I definitely think that the sprites need to be big, not small, so that they can be scalable. Maps will differ in scale, and it will be possible (eventually) to zoom in and out.
Regarding the array OOB... don't worry, it will work when I make the actual game. I just made the Test Artillery card to demonstrate my idea for the control scheme.
Maybe something simple like this, tinted to match the team color (I think it's TINTSPRITE?).
Or even just an empty colored outline of a unit, which also can be colored with TINTSPRITE. If it's white it matches exactly the values you enter.
And you draw a line to show the gun's angle.
And you should totally have explosions launch units based on the angle and the weight of the target(s).
I like those. I took a screenshot of a map, and then copy-pasted the first tank sprite onto it. It's a better combination than I expected. The all-color map with black-outlined sprites is kind of reminiscent of old-school Looney Tunes. Which is a good thing. Now I'm thinking that maybe an exaggerated, cartoony art style would be perfect for this game. Dark humor, deception, the dawn of the atomic age... so many ideas brewing in my head right now!
I'm not quite ready to put tanks in the game. My plan is to start with artillery, then add tanks, and finally infantry. Would you be able to draw an artillery gun?
BTW, I'm not sure what you mean about the explosions and angle and weight.
EDIT: I almost forgot to post the picture:
