I had similar issues to Mossieur Patate witht he loading the game was like click that error oh click here folder easy enough. The game it self I was not 100% what I was doing the best I got was maybe 5 or 6 blocks high it seemed to really hate if you are off just a tiny bit some times. Was unsure what the triangle was doing at first till I noticed it was killing the block some times or reducing my hearts on the screen. But other then that nice job on you game.
