Pong Break is a little flash game that I did… some time ago.
At he time I was using an engine called Stencyl, that permits to make visual scipting. The game itself is a strange mix in between Pong and Breakout, hence the title.
In it players control both pads, even though their directions are always opposed. The layouts of the tiles are generated from pools that become available depending on player performance. So some kind of procedural. Each time the player breaks a brick, a gameplay modifier is added to the list on the left. Once five of them are loaded, they start to take effect every 15 seconds.
To be honest, the game is quite hard, but I am still fond of that little thing. It is available as a public domain flash file from my github.
