After playing "field of flowers", I tried this one to see if it is better. But nope! It's like the protagonist from "field of flowers" is in this game too with the same whiny karen voice actor.
I decided to march through this game with Kamika's route, and I couldn't even help her take over the world, which would have been so much more fun then being a goody goody two-shoes, stopping her being evil, have that stupid drama and later getting along like friends.
And the ending, if there ever was one. It just cuts off so abruptly when Yumi and Kamika were having a moment watching the stars. It's like all my choices that led me to this point didn't even matter at all! No real ending, no more exploring of friendship or something more, no credits or epilogue. It ends just as abruptly as when satan nukes us happily.
If all other watercress games are like this then they are not worth playing at all.
