This is quite a nice TD, the graphics/sounds/music/design are all perfect for this type of game, also the models are quite detailed, it doesn't look ugly even when one zooms in.
Four towers is kind of the standard in other TDs, so I won't say it's not enough although, well, I could have imagined more variety.
Overall an absolutely nice game, I know, it's an old project, but I would like to see more.
Thanks very much for the kind words :)
Unfortunately a demanding job has taken away most of the time I had available to work on this project. It's been on the back of my mind for a while now- hoping to find some time to jump back and and flesh it out soon.
Appreciate you dropping a line- it made my day. Cheers.
