Viability: Game is playable from beginning to end. I think the affection being a number you need to raise is cool but I think it would look nicer in a separate box rather than just in the text.
Presentation: The rules were pretty straightforward. I do wish there were a few more options to choose from.
Theme: Theming is fun. Since the game is not very dialogue heavy I really think it would benefit from images.
Engagement: Entertaining. I love that you got a chance to name the griffin. I always like little befriending animal games.
