What an interesting setting. Kinda feels like Earthbound in a way (modern mall like setting, weird enemies, interesting/silly dialogue). When I got to the first shopkeeper I was impressed with how many items it had, so it feels like there's alot of potential for advancing characters.
The movement was good but turning felt a bit strange, like the camera was swinging on a center point around the grid, minor complaint. Also some of the rooms/hallways seemed big for big's sake and could have been cut down a bit, especially if there's no purpose served to their size. Maybe I missed them, but would have liked to have seen maybe some traps or treasure chests to reward exploring.
Solid entry, I'd like to see more of it!
