Woo! 103 score!
Great game! I like how since the triangles come from all different directions it keeps it from being as predictable.
Feedback / ideas for improvement - Maybe vary the time between triangles spawning in. Also consider adding in some sound effects for when a triangle spawns, when the player collects a coin, and when the player dies.
Cheers!
edit - If the global score / coins is supposed to be for any & all people who play, for some reason the 103 isn't showing up, but I do see the 42 coins I scored. :D
