It's amazing me that so many people are complaining about this change. As if their lives depend on getting the best score. Toning down the difficulty will simply make it so everyone can get the best score easily - and that's pointless.
This is less of a problem with people caring about the minigame and more a problem with people disagreeing with your attitude towards game balance.
In my opinion, making this minigame easier/accessible is better for the overall sequence. Your mentality seems to be that a "handout" is always bad. Had this topic been about an important story boss I would agree with you. However, handouts can be a good thing in game design. Great game flow is a constant push and pull of challenge and ease. This minigame is not something that I think is important to be difficult. Your mentality is great for designing formidable bosses, but it's a bit overkill for this minigame.
If multiple players are saying to you that this minigame is needlessly frustrating, then it's undeniably affecting player's experiences, and you should take note (which I see that you are, so thank you). You need to ask yourself as a game designer "Is this something that is important to be challenging? Does challenge here add to the overall game?" If not, things should be adjusted.
