Acid Drop is a video game released by Salu Limited for the Atari 2600.
Text from back cover:
Coloured blocks drop relentlessly down to fill the screen.
Using your joystick you must quickly spin, shift and align the colours of the blocks in order to clear them from the screen.
It's challenging and the pace is demanding!
But... satisfaction comes when you see the "ACID DROP" fall and disolve your highest lines and give you a new lease of life.
Need a tougher contest - start from a higher level! Pick your pace from the 30 progressive skill levels.
Hours of addictive fun guaranteed.
Acid Drop was designed and conceived by Dennis Kiss and artwork by Simon Cornish and Cameron Kerr.
