Xenomorph

Xenomorph is a simple dice-rolling game available for 50 cents at DrivethruRPG. You create a character by allocating points to four stats and then play up to 20 turns trying to escape an alien-infested station.

My "control panel" for Xenomorph: health, skills and turn counter.

On my first game, I spent three hours trying to bypass a jammed door, only to then face an alien and die in combat.

I started fighting a small xenomorph on my second game. It was easily killed. Then I found a shield that improved my defense. Then I found an alien scout and died again.

On the third game, I found a shield right away, then met a brute alien -- game over.

Conclusion
This is a very simple game, with very low odds for the player. Still, it works well to kill a few minutes. Although there are similar offerings for free, like Dice of the Living Dead, I think it is worth the price. The publisher also has a number of other mini-games at similar prices, and some free downloads.
