Fun idea and cute artwork showing unique touch with both sprites and scrolling effect. Nice idea on flipping countdown to positive thing. Unfortunately, could only test the browser versio that freezed at time to time so play experience was limited. I also saw your comments that things broke on last second, I always do that to my projects too while rushing to submit something :D
And congratulations on finishing your project! It isn't easy and your attitude is awesome, keep it up :)
