Art is very lovely. I think, this game have just one mechanic which is cutting trees, and there is a limited space. However, there was just 72 hours to make a game, so, i can understand that it is hard to make a game like this, because this project is more than a casual, arcade games, or puzzles. So, i think this game can be a really nice project for your future days. Because the theme, art style, and technical implementation are good.
