At first I thought this would be like the usual JRPG bestiary: nice to look at once or twice but no real depth to it. Boy, was I wrong!
The drawings are incredibly beautiful with chracter art that strikes a perfect balance between silliness, cuteness and design that can be taken seriously. Each character has a unique and charming personality that made the (mostly trial-and-error) dialogue options fun to explore. The diverse soundtrack fits the encounters perfectly: sometimes relaxed, sometimes upbeat, sometimes threatening, sometimes mysterious...the three composers did a great job!
Having played most of the other entries in this jam, I also liked your references to other cartridges of the Famicase exhibition. And the present after completing the bestiary was the cherry on the cake!
All in all: a creative concept turned into a flawless little game. Well done!
