Well, I have beaten the game. It lacked an intro for a demo but can't complain. So here's my honest review.
It feels familiar to games I have played before. Like oddessy of Gianna. That being said, for some reason, Celestia is the only one that has the give-up option. Which is a darn shame because it doesn't knock out the other princesses. Like how odyssey of Gianna knocks out the entire team. So, work on that first. Also, I would like to point out that you can take certain elements from Odyssey of Gianna and be able to wear a drone outfit so you can use its abilities. Because as far as I am concerned, Cadence doesn't really add anything worthwhile. And so, I figured that I can turn her into a drone and change her class into that of a drone. Have an entirely new move set.
Also, I find it dumb that you have to pay to heal but that's just my personal gripe.
Well, she doesn't have anything that allows her to hit hard. Her healing ability is just that...healing. And she has a double attack that she doesn't gain until later on. And even then, you can bearly use it at all. Either because you are using magic that. Most of the time, I am just spamming Celestia's magic to kill everyone anyway. The only reason not to lose Cadence is to make sure that at least one other pony is not fully captured.
I still say that you can for the most part use the drone ability after you beat the first level. Becoming a sort of super solider.
