The game I'm looking for was made for PC probably between 1996
and 2000. It's windows based. You may chose various modes, including tournament mode
which allows one to play four players against each other (on one computer).
The game looks like Bomberman, though it's a bit different.
There are four "dots" with different colour.
I think it's blue, red, yellow and green. The goal of the game is
to eliminate your opponents using bombs. At first you start with
the ability of putting out a single bomb. You may collect items
that expands the explotion radius and get the ability of dropping
several bombs at a time. It's also possible to turn yourself into
a brown monster (which is seen in single player mode)

I've searched for this game for a long time on different search engines, but
haven't yet discovered the right one. If anyone knows the title of
this game, I would be extremely greatful as I've almost given up
on finding it. Any help is appreciated
