Customizable screens/tiles allow tiles with more space. This would enable the integration of a slider for level settings instead of the up/down buttons.
The screenshot below shows a sample with 3 vertical sliders. Many other layouts are possible.
some thoughts:
The tile background would still accept touch events.
The slider handle (sensitive area) would be around the level only.
The handle ("knob") area could be made visible as thicker lighter/darker line when touched.
