+ The game is pretty fun.
+ The running animation is kinda hilarious and fun to watch.
+ John runs pretty fast which makes the game pretty challenging and more fun to play.
+The fast music adds to my excitement of running from John, nice one. ;)
-In my opinion you need to make the colliders more visible as colliding with them and not being able to move from some areas that seemed open to move from made it a bit annoying.
-More levels would make the fun go on. ;)
