You're pretty much correct! Though my game probably does need work in lots of areas, folks are saying that the theme is gnarly, that they had fun, that the art is cool (especially the pixel train turning), the train movement and eating people mechanics feel great, and the music and sfx are cool, so I hope I won't lose too much points based on how unfinished and not challenging it is :/ though I suppose that will probably contribute to the fun category.
I did say this to someone else but just in case you didn't see it... “the concept is you are exploring a theoretically deserted island with a derailed train and eating the natives to achieve isolation after escaping your crowded hometown in an 8 bit universe”
