I was quite impressed with the content Tim included in the 1.01 update. I’ve spent quite a bit of time with it now and put a lot of plays in to my Pro at home. All my comments are based on the Pro, so they may not be relevant to the Premium / LE models. Also, I’m not a comp player - just a person who loves playing my games at home 
There’s some good info above from people, and I certainly missed the important update dot point about Supers not leveling up in MB mode anymore. Thankfully someone highlighted this above! Since the 1.01 update, my retro MB mode scoring has taken an incredibly sharp drop. At first I thought that retro mode was not applying the multiplier, but perhaps that’s not the case and it’s the changes to supers that are the cause? I find it hard to judge as the display doesn’t give much away in terms of what’s active or what’s currently building points. In some respects I didn’t like (in v1.00) that I could hit retro mode and suddenly add 150 - 250 million with little effort. I like getting big points, however that rapid points increase made it feel too strong (especially compared with the points available from the average monster battle). But now the retro mode has swung too far the other way and feels of little value compared with monster modes. For a mini wizard mode that’s tough to reach (you have to beat several monsters + war hurry up to earn the knight letters to reach it), it simply has have more value. I’m not sure if there was a bug in the scoring previously that’s been fixed, or there is something off in the scoring now, or it’s just the super changes. But I feel the current state of the retro mode scoring (how the supers fit in and the lit shots) needs more attention.
One of the situations (frustrations) I’ve experienced over and over with the knight mode too that is if you lose your ball when the Knight mode is ready, your super progress is lost and no way to build it again. At that point, the best you can hope for is to activate a few supers at level 1 (provided you don’t drain from the knight target while activating them), which will only be able to reach level 2 when retro mode starts. Since the left VUK is the only way to boost them and is also used to activate retro mode, you’re stuck at level 2 and little value to be had in retro mode. All the effort to get there, with little reward 
On the topic of retro mode, I just passed 1200 games on my Pro and have never made it to the second retro mode. In fact, I’ve never beaten the Black Knight (only faced him a couple of times). I really wish there was another way to reach the second retro mode. It could be made simpler with more knight letters available, but that could devalue the retro modes.
On the topic of the Black Knight “monster” battle. Losing the ball here sends you all the way back to the start to the first realm. That’s more punishment than challenge (not fun) 
Glad to see the 250K and 750K awards from mystery removed and replaced with the 2 - 5 million instead. These feel much more in line with the game scoring. I think the points for completing WAR should see a similar boost in the next code update as it’s currently only 100K, which feels like it’s lagging behind.
The power sword fill boost for the first 2 uses is very welcome and I find this now much more useful in game. Also having the knight target add to the sword power is a big help and am happy Tim added this. This of course leads to more value from the monster modes and helps lift the average scores for games.
Bringing the pop bumpers into the war hurry up value was a good move, along with boosting the point value of the feature. I really like seeing the war hurry up show moved to the top too as this helps with completing it. This was another good addition by Tim. I still only go for it in MB (if I can help it) - but certainly has a lot more value and the update makes it more worthwhile to shoot for.
Additional points for successful magna save is good too as the original 550K too small for a successful save when compared with other areas for scoring.
Supers - One step forward and one step to the side here I feel. Taking super jackpot collection away from the left VUK is an excellent move. I never really liked that I was forced to collect it from a shot that’s used for several other things in the game. It felt like a poor design choice and I was being punished as a player for shooting a shot I needed to hit for other features. Having them now run without a timer and being able to boost and build them as I play is better. I do like this change. I’m not convinced that a player should have to sacrifice their magna save to collect the jackpot however. This now feels like punishing the player for another design choice in not having a second button on the side of the cabinet for magna save. I don’t necessarily mind magna save being on the lockdown bar button (I have no ties to the original games, so have no expectations on where it should be). But I think first press to collect should not cost you your magna save. Another option would be to have the player press the lockdown bar button within 3 - 5 seconds of hitting the left VUK, but magna save should be disabled on the first press during this period. Switch the colour of the lockdown bar button during this window to help players identify when it’s open to collect. It’s a tough one though as activating your magna save isn’t exactly reliable at the best of times and a split second for a second press can be the difference between success of failure.
I’m not sure on the best solution here. However I just don’t see the connection with having to sacrifice your magna save to collect super. You could say it’s risk vs reward, but to me I don’t see the connection of these 2 features. As it is now though, I hit the left VUK, then press the button and sigh as my magna save is spent while watching the ball travel along to rail to the return lane to collect maybe 10-15 million points if I’m lucky.
In short though, I feel the 1.01 update is an excellent step in the right direction with some nice additions to the rules. The supers and retro mode scoring still aren’t where they need to be though. So hopefully there are still more improvements taking place and a new update coming. Again, these comments are based on playing my Pro at home, so may not translate to the Premium / LE models.
