Orbt XL is a small game about orbiting a black hole and not crashing into things
It's simple, cheap, and a pretty decent price. The control scheme is simple(Left mouse button to go further, let go to go closer) and the gameplay itself is varied enough to be entertaining.
A few special cases mix things up, the obstacles are varied enough to be entertaining, and the gameplay simple enough to be easy to understand.
It represents a good price to value ratio, and it is pleasant to play for a while but it is certainly just a short thing to spend some time on and then move on. Worth picking up if you run across it bored or otherwise have a euro laying around doing nothing.
