I would suggest brighter colors overall
I kind of wanted a darker theme to the game. But I will put an option for shadows under the tanks, which would help them stand out better. I have already tested with shadows (their really just black gradient sprites underneath, shadows would be performance costly) and it seems to work well with the overall design. They might need to be coded a bit so they don't stay in the same spot when the tank changes direction.
I don't think you should need to hit a move button to move, instead just tap somewhere to do so. Also the aiming should be aiming in a direction and not at a tile.
I have thought about this myself and I would have to implement this into all of my codes. But I will mesh the aim and move buttons into 1 where you can alternate between aim and move modes. I don't think aiming in a direction would be best suited for the game I have envisioned, it would mean I would need to create one of those clunky joysticks and the smoothing of the aim would be much harder to make and would ruin the overall "quality" (if you will) of the game.
use brighter colors on the tanks. Make a more varied background. Make the tanks and their projectiles stand out so people know where to PAF and what to dodge.
actually holy forget get an artist
There will be a more varied terrain, this is just a placeholder (as is the shop) until I have finished the core of the game, then I will focus on the artwork. I have been working on making the tanks and their projectiles stand out recently. The projectiles already stand out enough with the lights around them and there will be sprite shadows around the tank.
It is quite hard to actually dodge the projectiles as they are now so that won't be a problem, although there is a chance that the tanks projectiles will collide in the air and explode.
An artist would be a horrible idea for me. My budget was zero so I am already $100USD over :|. Also once again, the sprites you see are just placeholders for now. I think I may only keep the revolver sprite (after some tweaking) from the shop and the LAV/Tank I have created.
