Both left-click and right-click currently rotate the image counterclockwise. Could you make one rotate clockwise and the other counterclockwise? This would make it more convenient to use.
There's a minor bug: when an image is dragged and dropped onto the icon buttons at the bottom, clicking the image triggers the button click event.
I passed with 740 kills after some attempts. Using magic tower with freeze is the easyest way to win. Some issues:
1, The use of weapons and the operation of tower upgrades often conflict with each other. Recommended to use double-clicking to open the tower upgrade process.
2, Red demonds is rare, after use up the initial 3000, I didn't know where can collect more.
3, Is Archer tower weakest one? I can't pass the level with archer towers.
