Hehe, I thought just using two characters was a lazy take on the theme, then I advanced through the game and well, there's definitely more than that but you already know this.
The game feels quite polished with very good movement and control feelings. Also a button is almost already enough for me to like it, I started by bumping onto the walls (even a bit further away) then went OK it must be a button then. A dungeon without dungeon mechanics feels a bit pointless to me so I'm always happy when people put some in their game.
That was cool, thanks for sharing.
Just ignore the question if it's inappropriate, but did you comment on my game just a bit earlier? I think I got an alert then saw a message then it vanished (I might totally have deleted it by mistake).
