Metoatsume

I drew this picture with reference to "Nekoatsume",a game for smart phone.

Nekoatsume official website ( hpmobile.jp/games/neko/ )
App store ( itunes.apple.com/us/app/nekoat… )
Google play ( play.google.com/store/apps/det… )

I wonder why there is no game whose purpose is caring for or collecting creatures in Metroid games. I'm sure that there is a good demand for such games…
