Interesting game. This would make a great mobile game with touch controls. At first i thought it's too hard but then i figured out the pattern where i was able to get through the gap with the right timing. After i figured that out, there was no incentive to play further though. I think i only reached a score of 5 or so, but i think some people would actually enjoy the repetitive motion you have to do and i'd say this would make a good game to relax and concentrate.
