SDBG is a simple Jump n Run game there jumping has a special status ;D
You have to collect some little stones and by doing this you have to avoid to contact some bad items in the level, if you crash against those things, you’ll have to start the level again.
You’re starting your game on a wooden board which follows your movements. The guy jumps automatically so some passages are a little bit difficult to master.
If you’ve collected all "stones", you’ll come into the next level and like it’s common, every level gots more difficult.
The graphic is monotone and the sound very poor. But for younger gamers, this game is surely a good non-violent one for playing after doing the homeworks.
