Dungeon Valley

Not my cup of tea. Looks good, simple to understand and play. I'd recommend it for kids or if you just need to kill about 10 minutes. The vertical "one handed" style is kind of awkward if you try to play with just one hand. Reaching across to tap buttons can lead to mistouches and be a bit of a stretch.  Movement needs recalibrate, you have to slide too far to trigger running, it makes turning awkward because of how far you have to move your finger to go in the correct direction and can end up stretching across the screen quite far.

If it had a horizontal screen mode maybe it would be a good game... portrait is the worst game format ever. Awkward to control.
