Devil Daggers is both simple in its premise as well as its presentation. It's the perennial "easy to pick up and play but hard to master" game coupled with a touch of "only one more run before I quit the game" addicting mechanic.

This is a first person shooter with twitch-based gunplay consisting in defeating endless spawning enemies from hell. New enemy types spawn as you progress. The game ends when you die and your kill-count acts as the game's scoring system which is recorded and posted in an online master leaderboard. The kick is that the game/enemies is brutally challenging and hard so it's fairly common to die quickly and the rinse and repeat the process. Overall, I enjoyed the simplicity in the concept of the game as well as the them and presentation.
