I personally really liked Mononofu, like this game version of Mononofu too. However, I don' t see posibility to look into items inventory and it is even more disturbing that there are no battle skiping possibility.
There should be possibility to skip battle than you already reached 3stars in particular stage. Currently everything is new, so it is not boring - however, later than we will need to farm 1 particular material without skip - it will take hell of daily time and will be extreme boring.
