To Start A wave, you click the gray button under the money counter, But you wont be able to stop the wave or access the shop until after the wave. Also In the shop, use the left, right arrow keys to move between different guns. Click the gun you want (and have enough money for), and You will have it and place it anywhere,
Also For some reason the tower shooting code stopped working for most of the time working on this, but in the last 2 days, I fixed some code with the "distance to enemy" variable and it worked again! :)
