Quoted from vicjw66:

No it has a very repetitive rule set and very repetitive and glitchy sounds and dots. It is hard to play in the sense that it is so painfully bad it is hard to play without wanting to quit playing. Gameplay is in fact easy. Just lock a ball. If you then later drain, that locked ball releases back into play. Think of it like Sonic the Hedgehog. As long as you have a ring, you won’t die if you get hit. The only real thing to do is spell International Rescue, which requires you to shoot the ramp to nowhere 19 times. The ramp shot is one of the least satisfying shots in all of pinball. Nothing special happens once you achieve this goal.
