Polygon, polygone

Controls:

Mouse to aim

left click the red and green turret in phase one to open shop

left click the yellow slots to select and buy items

right click to exit the shop

space bar to buy more vehicles in the last phase

Build a assortment of defenses and survive against hordes of Polygons. 

Each piece of equipment is permanent once equipped, so choose carefully and plan ahead.

Some weapons are better suited for different parts of the game.

The game is split into 3 sections.  You start out equipping two turrets to defend a stationary core. Once the core is ready, it will "scale up", taking the turrets and become mobile. You will now be able to create a vehicle out of the turrets you've built. Finally, you will be able to "scale up" one last time and purchase more cores, creating a fleet out of the vehicle you've built. Remember to make sure your contraptions are "Built to Scale".

(I didn't have time to fix a fatal error thats happening on restart so you'll have to relauch the game each time, sorry!)
