Tower Defence .. V.4 :D Not bad, could use some work however
Its pretty good for a beta/alpha version, however, a few things need some work. First of all, the placement regions of the towers need to be adjusted, because in certain areas, mainly on the horizontal sections of the path, towers above the path can overlap the brown a bit, while towers below the path have to be much farther in on the green area, as if the collision and visual layers are slightly off. Also, instead of starting out with a large amount of money in the beginning, try decreasing the starting amount, and increasing the amount awarded for each enemy killed, as well as decreasing upgrade prices a little. Once you do that, start the enemy waves off with less numbers while slowly increasing numbers and difficulty. And boosting the graphics some more would also help, even though you current graphics are probably just placeholders, try to make them more appealing i.e. shade them, add stuff to them when they are upgraded etc. Other than that, a pretty good attempt, I hope the final version is awesome ;)
