Really simple gameplay, but when you see yourself grow more and more and destroy things much more easily, it becomes really interesting to see how big you can get and what is behind the trees on the map :)
The only thing I wish was changed is the movement speed - I wanted to explore more, but moving back and forth was really low for me, so I only found 5/7 clones of the wizard :)
Also it would be cool to add some health indicator for enemies, especially the end boss :)
