TANK GAME IDENTITY HELP

[LEO4LIFE]

Hi All-
I am trying to find out the name of a game I used to play back in the day. To best describe it was that you were a arcade style tank, surrounded completely by blocks that were different colors. You have unlimited ammo and would destroy these blocks and depending on the color they might do different things, i.e. explosive chain reaction etc. Also, there was a random spider like creature that would attempt to attack you throughout the game. I know there is a green colored tank game that most played but that is NOT the game I remember. Thanks so much for all you do here!
