Very nice graphics and idea. However, you might need to work a bit on the gameplay as for example I was not really able to throw the vases and sometimes the physics felt a bit strange (hard to explain :) ).

You might need to check the challenges you selected, I do not think it fits in the js13kGames category.

Good graphic, but text and gameplay more repair again. 

For some reason, the bird took away my stone and began to walk further without the stone. This is fine?

Bird, give back my stone! I want to continue my Sisyphean work!

Doesn't fit the js13kGames rules

very nice character model and movement animations.

The core idea is so good. But it is hard to play because you accidentally pass the rock and when it is behind you need to start over, or am I missing something. Yeah Sisyphos story is about starting over but the rock is not rolling, I am going too fast for the rock :) Maybe fast walking would be good. But like I said the idea is very good, you can create a Bennet Foddy style game from it.
