HTML5 Web version ( Firefox-only! ) : http://code.alaiwan.org/games/LD/invaasion/game.html
Build turrets and defend your land from the invaders!
How long will you last?

Each turret type has its own characteristics : rate of fire, firepower, rotation speed, ... and, more importantly: metal cost.
You have a constant rate metal income, kill invaders to get more metal units !
The music is a tribute to two classic NES games, will you recognize them both ?

Good game and thanks for the upload!!
As for the game itself, the graphics and music have a pleasing old-school theme to them, and I like the freedom of being able to place towers anywhere you want instead of being restricted to a path. The fact that you even built the engine from scratch only makes this more impressive. Well done!





I'm a sucker for tower defense.
I tried random towers. When I realized that towers die when aliens touch them, I thought I'd make a wall with the cheap towers. But that turned out to be wrong, I needed more firepower.
I made a [sheet comparing DPS per cost of units](https://docs.google.com/spreadsheets/d/1MSVi8jfXR7vL3eK1gPRnOWmNDLUYOxdvMTD4kqV2F6E/edit?usp=sharing). That got me to the 560 score. Then I tried a purely long-range M29 strategy. That sucked, because of the low fire rate I only made it to 220. So I went for a purely XW2 strategy, as they have the highest DPS per dollar with the #2 range in the game, and the #2 highest fire rate. Making a line of those got me up to 650. And I don't think you can go much further than that with the current game.
It would have been great to have a 2x and 4x speed modifier. It got a bit boring to wait out sometimes. Still, I had lots of fun. Thank you for the game!
I don't know if there are strategies better than others but I think the game has potential.
