Marble Madness

Quite an interesting game. You have a balloon at your disposal and you have to get it to the finish line within the allotted time, using the terrain and various jumps. If you fall into the abyss, you lose time. The game is very addictive, and you can sit for hours to complete a particularly difficult level. If you play together, there is also the effect of competition. Conclusion: download it, you won't regret it.
