Upgrades are coming!

This is the last update for the day, I have added one upgrade to the green tower, more upgrades will come now that I know of a way to handle them without it being too ocmplicated

-- Green tower upgrade doubles damge (will be tweaked after it is bug tested) and costs 10 gold to purchase

-- To upgrade the tower just click on the tower once it is placed and in the bottom you will see the icon pop up, clicking on it will do nothing unless you have 10 gold. If you wish to get rid of the icon in the bottom of the screen (even after clicking a sqaure to buy a tower) just press the escape key and they will go away until you click on a square or on a tower, you will see a label named instance ID this is for debugging purposes only!

Thanks for the continued support! I look forward to adding more upgrades in the very near future. If you have ideas for some unique upgrades feel free to send them my way!
