Not 5 stars only because it's unfinished. Have played up to beating Cynthia, I'll probably stop until there have been some more updates.
Game is a lot of fun right now. Has a longer, slower structure than a lot of other games, but in my opinion that's a good thing. It's fun to think about how to structure my teams to do content in the best way, and I'm interested to see where it will go.
Still some bugs to work out but that's to be expected while the game is in early access. One frustration in particular is that editing a mon's moves while sending them out to an area will cause that expedition to glitch out. Easily fixed by recalling the team and sending them out again, but it's still annoying to work around. There's also currently a glitch where evolving Paras gives you Slaking instead of Parasect. Be careful leveling up pokemon whose evolutions haven't been added yet too, seems like evolution only triggers on level-up so if you hit level 100 there might be problems.
