I get more requests for adventure games than any other type. Here's an arcade style action adventure, Torn World.  You get to choose your character's class. Initial choices are  knight, wizard and amazon with three additional bonus characters that are unlocked after reaching a certain level.

The game plays well and the basic strategy seems pretty easy; get gold by running into floating golden orbs and kill everything else that moves.  This version is designed for 128x128 screens, making it ideal for the i290, i355, i425,, etc.  It also works well on the slightly larger 128x160 screens of the i776 and i465 but fills less than half the screen on the i9 and i856.

Keys
5 - Use weapon OK, Select
2, 4, 6, 8 - Move Up, Left, Right and Down

A rather bare bones recreation of  DOOM, which is generally credited with originating the 3D first person shooter video game genre.

This mobile port is quite old. It's single player and the graphics are rather crude. The game seems to be designed for 96 px wide screens. Even on low end phones like the i290, the graphics don't fill the screen. But the dungeons are huge, the game  is responsive and the controls work well.
