There are some bugs and flaws that exist: the attacks seem to target the user (?), the doors are front of the player character when exiting a room, and the walls on one of the corridors can be walked upon. The battle system lacks significant mechanical interest even within the default RPG Maker scripts.
The idea of a cat RPG, while moderately novel, needs to be backed up with some refinement. This is doable, and I hope with some more time it can develop into something the creator and others would like.
