Anything that involves CG is absolutely worth checking out, especially if it gets her arrogant/grumpy personality right, I don't care if I'm biased.
Some say is absurdly hard and I feel like quick time events either are slow no-brainers without any real stakes or they're so fast you can't react properly. In this case it gives you just the right amount of time to do the inputs which is the ideal way of doing qte in my opinion, and now with the patch it should be easier to do so, just don't slack off.
It's true that's very short and feels more like a micro game, but making this seem as a big con is like thinking about it for what it could be rather than what it is, and what we have here is a fairly small game of basic premise with a straightforward task that doesn't waste your time by making the process nedlessly tedious, also the reward is brief but still worthwhile. I'd even say it's a bit replayable due to its short length.
I would love to see this game getting an extended version, it definitely has the potential to do more with CG or characters related to her (even if it doesn't make sense to put them in the same situation), or a harder mode where she has more clothes and the inputs get more tricky. But as far as I know this wasn't ever meant to be more than a small project and totally free, which I think is fair to consider if you compare it to other games of bigger scale. So for what it is, definitely worth playing.
