Wizball

Wizball is a scrolling shooter in similar vein to Gradius with an additional collection dynamic. It is a horizontally scrolling game taking place over eight levels, which involves navigating around a landscape and shooting at sprites.

However, the aim of the game is to collect droplets of coloured paint to colour the level. Each level starts off as monochromatic, drawn in three shades of grey, and needs three colours (red, blue, and green) to be collected to complete it.
