Castlewatch

Seems like a fun game, with a lot going on. There are five basic types of towers, and one additional that doesn't shoot but can block the path, and eventually has a buff for near-by towers I think. The five basic types of towers have (I think) six possible upgrades, but each tower has three special types that can split off into as well, so a lot of decisions to be made. These are strategic upgrades, where you buy access to these later upgrades. The towers also allow for prioritizing targeting, a nice option. These is some variety to the foes, fliers, walkers, swimmers, which is fun, plus some seem to have special powers. I saw a walking death that seemed to summon critters as he went along. The graphics are primitive, but serviceable, and the music simple but not annoying. All in all a well thought out and fun Tower Defense game, two thumbs up. ADDENDUM: 25 hours in, and still enjoying it. A wide variety of styles and types of towers, maps and foes, as well as a deep and interesting collection of upgrades. Tower Defense gold.

One of my favorite tower defense games. I love Castlewatch because of it's simplicity. I wish there were an easy mode though to really utilize a lot of your fully upgraded towers. Easy pickup, and a lot more maps than the demo. Highly recommend.
