Grumz

Grumz is a vertical arcade game where you move a polyhedron up and down along a line in the middle of the screen, trying to get the highest score possible. To be successful, you need to dodge all the other objects coming at you from both sides of the screen.

The gameplay is simple: you get a point each time you hit one of the walls, and the only thing you can do to avoid the other objects is touch the screen to stop moving. That said, you can only stay still for a few seconds, so make sure you think before stopping.

From time to time, you can find power-ups coming from the sides of the screen. You can use these power-ups to increase your speed for a few seconds, destroying all the obstacles in your way.

Grumz is a beautiful arcade game featuring a simple and fun gameplay. It's one of those games that's great for short rounds whenever you get a minute to play.
