This is a port of LBreakout2.
This is the highly polished successor to LBreakout.
It is a breakout style game with nice graphics, effects and sound and what's more comes with an integrated, full featured level editor.
If this wasn't enough you can challenge other people via internet or LAN to either deathmatch or normal levelsets (untested!). It's also highly configurable via an option-packed menu.
Full source is included. Note that long filename support is required, although the game will run from the Archive.
