Great concept but...
First of all i love this type of game really fun and a great thing for those who like to get all achievements. I love the art for the game.
On the other hand this game is buggy, there are 3 things i noticed in my game play:
1: the boxes and other movable objects are floating and have a blank space around the them, the game treats that part of the box as an object making it very difficult in game play.
2: the re-spawn is really awkward, after dieing it first brings your "body" to the start then to the latest checkpoint.
3: the cows movement is awkward/unresponsive always afraid I will fall off.
I hope you would address these issues soon. So i can play it =D
