I like the event a lot. The 2 questlines, the chests, the rewards, I like it.
2 things I don't like:
I reached the end of one of the questlines, so all that is left is the daily reward. Doing the quests was fun and I am disappointed that there isn't more after producing the 50 beverages. I hoped there would be much more, so it would at least keep me busy for another week.
I only have 30 sun flares, so the second big prize won't be reachable and that doesn't feel good. Of course I will get the daily reward and that will make it possible to open a bronze chest every other day. The rewards are nice, but I can't reach the second big prize. Now I understand that you need to earn money and you want people to spend diamonds. I also think the big prizes are very good. But I feel it should be possible to be able with daily log in and doing all the quests to reach at least the second big prize. It should be hard to reach the second prize, request a daily log in, making me wonder all the time if I will make it, but now after a week I already know I won't make it. I also wouldn't have the feeling about the need to spend diamonds if the second prize would be reachable without diamonds.
In the beginning of the event, we got an offer to buy moon splinters with a discount. I think that was way too early.
So I feel a bit disappointed, while the event is so great.
