I've played this much longer on Switch after the official release since I really enjoy the portability, so don't let the 27 hours playtime fool you. I've finished the game, collected all the monsters, and cleared all the bonus content, so unsurprisingly, I really enjoyed the whole experience!

+ Monster balance and diversity is the star here. You can come up with sooooo many viable comps. That could be a little overwhelming, but I never found that to be the case.
+ Combat is great. Rewards understanding of mechanics, and it's lots of fun trying to get full stars on champion bosses, and check out other people's teams (some very creative people out there).
+ Love the metroidvania aspect of the game, very nicely integrated into the genre. It was lots of fun re-visiting areas after getting a monster that has the ability needed to overcome some obstacle (swimming, flying, etc.).
+ Great design on the monsters, and very nice world.
+ Music never got boring and nicely matched the different zones.

- Story isn't the selling point on this game, although it had some interesting twists, so this should not be a reason not to enjoy this great game.
- Future update will include a way to add notes on map to remember places that need revisiting. On the Switch I just took screenshots so it wasn't too bad.
