I liked the idea of the game. There could have been moments of mad dashing trying to dodge the flies and pinning them on the wall, but it just quite wasn't there. Perhaps with a little more time. I also don't think this quite fits with the theme because there weren't any systems or mechanics in the game that were "joined together". Joining flies on a wall is like DOOM joining bullets to a demon's head. Same thing. Sure there were combo points, but it wasn't enough to encourage me to play differently. Perhaps if there were consequences to joining too many to a nail or the wall, causing a boss fly to appear. There is potential though.
