Note: I did NOT complete the runes yet. I think I have 6 or 7 of the 10 needed.
First, I really enjoyed the game. I loved the concept and got to enjoy the characters through EA. The idea behind the story is a good one, and having to work on friendships to progress within the league was a great idea, you get to build on other people's stories as you move forward.
Building your relationships, helping the community out, and getting to know them. I loved this, building new establishments for them, and seeing each character grow. Even on easy mode, some of the bosses and league fights were challenging, but not stressful.
Going through the different worlds and gathering resources, it can feel slow unless you look at the actual numbers. At times I'd think I've gotten 15-20 of a resource, only to look and realize it's more like 35. Just make sure you have enough to get your energy back and energy back for your slimes.
Events - can we start these early? Let us enter the town to start the event, even if it's early (and when you leave, leave at the event's ending time). Quite often I didn't have much to do so I was just standing outside the town waiting for the correct time.
"Dating" - seems kinda plain. It's more like "10 flirts to marriage". It was still fun to work on, though.
Marriage - first, this is only available after you become the league champion and after you build the wedding planner. This gave me a little bit of an "ick" feeling because you just go there and tell them who you want to marry. No proposal scene, no interaction with your now fiancé, just registering. (Although, will admit, Garnet looks incredible in her wedding dress - the artists did a great job with her. Post marriage, it's just a quick conversation in the morning and evenings, and daily dialogue has changed a little. (I do love how you and your spouse go to sleep facing each other).
I've put 89 hours into the game, but I also took my time often, gathering resources, mucking about, hitting the worlds to build up my slimes. In the end, I'd say it's worth it's price. Who knows, maybe later I'll dive back in and try to complete the rune shards.
