A decent start, but not without issues: the controls are a little clunky, both in terms of the visual cue for shot power being very small, and it being fairly low detail with only six bars; the graphics are fairly dull and could benefit from greater variation between levels; and the physics part of some levels can be inconsistent (specifically in my case the final level took three attempts before the top right ball would roll far enough once hit to knock the top left ball over successfully).
