Viability: Not playable to the end as this is a demo. I did get a few ending paths which were quite funny. I think each path is funny and work together well!
Presentation: I think the user interface is nice and how to progress is understandable (even if a bit crazy like a henry stickmin game) . I think adding some sort of box around the text however, would help me see it a little better.
Theme: I don't really think it has too much of a direct theme. I think it does have a concept, and that's to be funny. It does achieve that concept quite well! it is funny!
Engagement: Yes this captured my imagination. I very much could imagine playing a board game with a skeleton. very fun!
