This is sooo cute. As someone who had Tomagachis as a kid, this was really nostalgic. The art style is wonderful, and I loved the sparkles added whenever you got a new stage of the pet you had. Also the multiple choices for the case around was a good touch!
My only thing with it is. as others said, it gets a little bit repetitive. I'd love to see some little mini games while leveling up my little friends in the game :)
Super cute though, and definitely relaxing. Great job!!
