This is Bananattack.

Quest for Colour is a time-critical game, where you battle against the clock while the world gradually deteriorates into greyscale. You need to collect the three crystals: Red, Green, and Blue before the time runs out. You can also pick up Color Bits (that look like tiny colored dead pixels in the game) to extend your time, but you need to run!

It was my first ever competition game, and was made in high school, so I hope you can excuse the oddness of this entry.

I recently updated the tileset graphics, made the time limit visible, and enlarged the color bits so they’re easier to find.

Remarks: Not for color-blind people. Interesting idea, but still needs way more than a facelift.
