Card Maps - Tower Defence Game

This is a simple tower defence game made for the OMGJam 6. I only had 2 days to do this with very limited internet access so I hope this looks okay in comparison to the other entries :). 

The aim of the game is to complete the 10-15 waves in each level within each difficulty level, easy / medium / hard. You have 3 options of defence, found in the cards at the bottom which can be clicked on and then placed at one of the given locations on the map. Good luck and I hope you have fun to anyone who is going to play this!
