The comic seems like an . . . unusual choice, at least to me. I'm curious how you'll make that into a game--let's check it out! :)
(after playing the game)
Oh. So that's how you make a "game" based on this comic.
Honestly, when I read "filler mechanics" on the title card, I thought this would be a game that explored tedious mechanics in various ways, so in that sense this was a real letdown. But I do have to acknowledge that the game does interpret the original comic quite well, and I do like the little details; the hover text in this game is very "xkcd". My main complaints would be that the "filler mechanics" title was completely half-chopped off when I played it--I play on Windows, btw--, the music gets annoying quite fast, and that this really shouldn't be called "Filler Mechanics" at all, imho, since it's really not about mechanics. Maybe "Filler Game"?
Good work on this.
(Also I think the 3rd reference might be this comic? But I'm not sure.)
