A few problems, but not too bad.
Starting score: 5
+ Generally fun (+2)
+ Addictive (+1)
- Orb sticks to walls (-1)
- Deaths reset between levels at times (Intentional? -0.5)
- Level 25's starting point is in the path of a pink stick, causing one death to trigger six more (-1)
- No music or sound (-0.5)
Overall, a fun game, but it needs some tweaking.
