Arrow keys to move, as usual. Your score and what level you're on are on the top, should be easy to figure out which is score and which is level. High score (on the cloud) is under the crown. The levels get progressively harder (or should). only 19 levels, but I may add more. I started on this game a looooong time ago, but forgot about it, and then found it again and decided to update the code, and make it good. before it only had 5 levels, and they weren't even the first 5 levels.
My personal high score is 1893, out of 1900, which means I died 7 times, so, not bad. I don't really feel like improving my high score, but I did actually get 1900 once using a glitch, but I fixed that. If you experience a bug tell me, and I'll fix it, if the high score is over 1900, comment saying somebody decided to cheat, and I'll set it to 0(if they actually cheated to get it)
