Some ideas to improve the gfx:
- quick screen flashes (maybe just for the background parallax or just some color gradients?) for explosions
- trembling screen for explosions
(the 2 ideas above come from Worms DC for the Amiga)
- sprite deforming when they bounce. IMHO the Hedges are a bit rigid and a very little circular->elliptical smooth deformation after explosions, when they start bouncing around, would be cool... At present they look like steel-made
