Help me find the name of an old CTF game I used to play

For the past month or so I just cant seem to get the memories of playing this old game out of my head. Please help me in finding the name of that game so I can get some closure and get it out of my brain!

It was a team based CTF game.
Its VERY basic in terms of graphics. Only shapes and blocks, no textures or anything. Even the characters/players were just basic poly of a humanoid.
You play by throwing blocks at the other teams fortress/base and players and try to capture the flag. This is the only weapon. This was most likely a childrens game.
Two teams - Red and Blue.

A notable detail is that the characters did not have any body movement or animations, you held the brick/block you had to throw with both your hands above your head and when you press mouse1 it just threw the block in a trajectory.

You could cycle different shapes (cubes, cylinders, pyramids)to throw using right mouse(.. i think, memorry is a bit fuzzy)

Its not a very old game, should be somewhere in the year 2005-2011
