You could add a fast forward button, auto next wave and pause button. It'll be good to have an indicator of what enemy will be invading on the next wave. Also, its nice to have it cancel the upgrade/sell menu by clicking outside of the menu. A sound effect such as unable to upgrade is helpful too. [Bug] When I had $100, I could not purchase HandGun.
To developer: For the shop, if the item is already purchased, I suggest that you do not show the same item again. Whats the point of allowing me to purchase the item when I already own 1?
I couldn't view the health bar of my army. You might want to place it above (somewhere easier for us to see). Secondly, show a timer of when the regenerate, shield buff is going to expire. thirdly, the icon of the army should be more expressive? For example, the axe weapon does not show up in my army even though I have it equipped.

i click a tower, i tried placing on the map, but it doesn't place it down :O
I tried hitting the esc button to cancel my selected choice, but it doesn't work.
I tried clicking on another tower while the first selected tower is in my cursor, does not work too.
thanks a lot, I corrected the bug
