I noticed how izone implemented Bomberonline, a game created by eurocenter..
i once use to play bomber online and it was pretty good but i think the bomb spar needs much tweaking to reach the level that bomber online has.

It's hard trying to control how the character places it's bomb.
so i suggest removing the arrows that show which direction to place the bomb.
This may be a bit confusing; however, if a character is already faced in a certain direction, i don't think it's required to change a certain direction when planting the bomb. it's useful when using guns but not in this type of spar..
because of this.. it's easy for players to get stuck in between their own bombs and aren't able to control the movement of bombs basically

Also the boxes doesn't seem to help in certain occasions..
it's easy to get protection yourself when a barrel is in the way supporting you but if there's no barrels at all, and you need cover.. it may be hard trying to get be hide the box without slipping off of cover.

Also i think the delay of the bomb explosion should be changed. I'm use to a face paced game and always seem to die after the bomb has exploded. (even when the bomb has faded to the tiniest bit) so the explosion time period should be lowered some more...

Also, heres where it may get confusing.. when a bomb explodes, and you were to push a bomb towards the explosion, that bomb doesn't blow up.
it's very hard to explain with out showing you the comparison between the spar in izone and bomber online, i do love what you added to the game and i hope my suggestions are implemented.
