Hi, your game is decent, but I have a few suggestions which I will list off in what I see as "order of importance":
Important
I'd change the red square icon for the game as it may give players the wrong idea. Even if you just have to use another placeholder icon.
Medium importance / affects perception:
The graphics aren't too bad, but I'd change the green texture on the top part of the trees. I feel it doesn't really fit the game and doesn't look realistic.
Small suggestions / doesn't really affect level of fun:
I'd darken the color of the texture on the staff a little (while keeping the lighting effects on it), and decrease the amount of blur slightly of the clouds.
That being said, otherwise this is pretty good. It ran well on my computer.
