Big mode reminds of those multitasking flash games I used to play, except all prettied up in a great-looking and thematically unified package. But even with that similarity, I don't think I've played anything quite like it. Really great job. Small mode also looked great, but I found it much more frustrating to play. I don't know if I'm just really bad at it lol but it seemed like there were some attacks I just couldn't get away from. Overall though this is a great game, and works with the theme nicely. Hard to imagine a better realization of "Big Mode" :)
P.S. great job with the story illustrations, and even better job bringing the 2D art style to the 3D models
