Congrats you made a very addictive game! Addictive in the sense that it makes you want to keep playing just to try to improve your score. Best i could get after 10 or so solid tries (Usually getting to the the 45-50m mark at best) was 64m so not quite good enough to beat your score screenshot on the game page.
So yeah nice job on the game it is hard but not to the point you don't want to try and try again to do better and the difficulty makes you believe you can. That is the replay factor sweet spot hard to achieve in games. The Beaver Dam 'Those Dam Leaks' invokes gives a similar feeling.
Thanks for the experience!
