This is kinda fun. I think it would be more enjoyable if the camera didn't move with the square, that way you could see more. Also move the player to the left and overall have slightly less hexagons. Then it is way easier to play with skill and not just luck.
I got to about 100k score when I noticed I gained more health than I'm loosing while just standing there xD. Also the performance on the web starts to be laggy quite early, but what to expect with thousands of physic objects on a single thread.
