This game is surprisingly expansive and creative. There are some points that could be polished better that keep it from being a home run, but overall it's a good game.
My biggest problem with the game is the writing. The grammar issues really mess with the message the game is trying to convey. The writing in general could use some refining, too. Like in the beginning, why does Mira suddenly vomit? It comes out of nowhere. Likewise, it's not clear what happened to Mira's sister. I don't want to go into too many spoilers, but there are several times in this game where things just seem to happen without proper explanation, and although this is a dream world, it still comes off as incoherent.
I did like the custom art (especially in the very customized main menu), and the battle system is unique. The deliberately crazy maps, complete with scrolling backgrounds, really bring out the sense that this is a dream. My one complaint would be the transition points between rooms: Many early maps have tiles that indicate a transfer to the next room, but only one of those tiles actually work. Also, I get that this is a dream, but some of the transitions are so disorienting that I thought my character had turned invisible a couple of times. For example, on one of the maps, we're going up and transfer at the top of the map. On the next map, we're on the far-right side of the map facing left. The lack of consistency makes it confusing. The battle system with the expressions is interesting. The scrolling backgrounds are a bit much; I'd just go with a static background, but it's definitely not your run-of-the-mill battle system. You managed to add just enough variety so just after the battles get grindy, something new happens and keeps me interested. Also, the battles aren't too long or too hard, and even have some story elements occasionally. It's hard to get a front-view battle system to work well, and although I don't think it's perfect, it's good!
I ultimately did enjoy this game. If you keep developing this game, I would recommend really refining the story, especially the grammar. Good job!
