Let's talk about Tidal Wave.
During this timed mode, the Left Orbit, Upper VUK, and Spinner Lane feed the ball to the Upper Ball Launch and awards 20M. The ball is then kicked up around the Right Orbit to the Upper Left Flipper, from which the Side Ramp can be shot for a Rescue Award of 50M. Getting Rescue Award three times will complete this mode where you receive a 50M Completion Bonus.
That is original description of this mode... but in reality, this one is buggy! The way it currently stands, it is very hard to actually complete this mode successfully for a few reasons.
Here are the problems:
1) When the mode first starts it offers up a "Shoot the Side Ramp" along with the jet-ski girl animation. However, if you make this very first Side Ramp shot correctly the game does NOT count this as a successful shot! You still have to do this three more times!
2) If you are slightly late with your Side Ramp shots, the game will show a "Rescue Successful" animation... however, it does NOT count as a successful shot, very deceiving!
3) Every time you make the Left Orbit, Upper VUK, and Spinner Lane shot, this counts as one of the three attempts. After these three attempts (regardless of whether you successfully shot the Side Ramp or not) the mode ends! This means if you do not perfectly make all three Side Ramp shots then the mode ends and you do not get the completion bonus.
All the above issues are now fixed. Now every successful Side Ramp shot counts (even that first one). Also, the failed attempts at hitting the Side Ramp do not count against you towards the three attempts. The mode ends when either the timer runs out (unsuccessful mode completion) or you make the three combo Side Ramp shots (successful mode completion).
Another change is the upper gate will now open faster with the Left Orbit shot during this mode. I know in the current game, this gate often does not open fast enough and the ball doesn't get to feed down into the Upper Ball Launch. I have made this gate open as fast as possible so hopefully the amount of misdirected balls will be reduced. Similarly, the lower gate opens faster with the Spinner shot in an effort to allow the ball to properly make it into the Upper Ball Launch with this shot more consistently.
With all these changes above I think this mode now plays as originally intended by the designer, and the player has a fairer chance of getting a successful completion. (And remember, each successfully completed mode increases the amount that the Earthquake Jackpots are worth!)
