The game has harder shots than most other recent games. The good news is that the harder shots are those that aren't used all the time. I would say the right ramp and the left orbit are the two hardest shots, and I find the left orbit to be pretty consistently. So basically the right ramp is hard.

Honestly, the only way you hear "who brought the dog" too much is if you are an idiot. There are two other mode paths, and both of them are shorter if you are trying to get to the mini-wizard multiball.

My list of cons:
The scoring can be pretty imbalanced, but that's salvageable with an update to the multiplier rules.
Modes need to be easier to start if they aren't lit
NEEDS to have a simpler Slimer 2-ball that's easy for new players to get to, but doesn't have to be worth much. Make it worth about what Storage Facility is currently worth now and bump that scoring.
Make a Super Jackpot actually a Super value.

With an update coming (nothing like being told that for 12 months) and the recently released ColorDMD, there is going to be an uptick in interest in this game. Is it the best? No. Is it hard? Yes. Is it really good? Yes.
