Its nice game with cool mechanics and nice animation.
However there are few things I would like you to clarify within the game.
1. Why are the clocks present ?
2. Because the clocks don't kill player player goes and collides to the moving box which kill him, this is annoying
3. Instead of bottomless pits add something like lava or spikes to kill people
4. As there are bottomless pits people often feel the urge to check for easter eggs. However after few unsuccessful tries it becomes annoying too.
5. The green points in middle of the game don't work, I assume you are planning to make checkpoints which in my opinion is good idea.
Everything I listed is just my opinion, it might be different for others. Anyways it was still a good game :)
