Interesting idea for a game! At first it seemed to be more of a SIM, but with a storyline woven in, and battles, it seemed much more interesting all of a sudden. Love the happy music and pixel graphics, and the slick interfaces, even though the instructions are a lot to take in. On the first screen, when you enter the room, I was trying to open up phone/instructions/etc to no effect, maybe have them unselectable or something until you clear that first phase of going around the house?
Feels strange having the cubes hide behind each other. I imagine being able to place them on top of each other instead could make for some more more co-ordinated movement. You could move the lower one to move them both, in battle for example. Always have both visible even with limited surface area, etc.
Anyway, the game seems promising! It's more than you'd guess at a first glance: a SIM, a dungeon-type RPG, a point and click adventure... going to be interesting to see how this evolves before final form! Good luck with the project!
