"There can only be one!" I quite like the concept and the presentation is decent, the timer and sound that goes along with definitely needs a change, perhaps doing away with it entirely and instead making your parallel selves increasingly aggressive as time goes on? I also think that perhaps merging with your other selves is a bit too easy especially since it makes the game easier as you do it, what I originally thought you'd have to do is sort of mimic the motions and stay "synced" up with them for a short while till you merged, not sure if that'd be fun, but, I think that or some other added challenge would be cool to have. All in all it's a fairly fun game, nice job!
