IF THE GAME STARTS BEHAVING WEIRD JUST RESTART. One sign something is wrong is when a few blocks "join" but their graphics do not update to show they are joined.

The goal is to kill the enemy "base" which is the block in the top right corner. You must defend yours. Pretty sure right now it's a one shot hit to win the game. I'll upload the linux build soon, with web to come shortly after.

CONTROLS:
Select unit or cluster: click
Plan move for unit: WASD or Arrows
Pause (restart available): Escape

It works okay, I'll update with better instructions later.

Click pieces and move them with either arrows or wasd. Every 10 seconds pieces will spawn in the center randomly, alternating between you owning them and the AI owning them. For the first ten seconds the pieces are on the board you may move them very quickly. After this time period, the pieces are still moveable, but will only move every 2.5 seconds. Getting a block to contain a 2x2 configuration will bolster the health of every element in the block to 3. A 3x3 block fires every 5 seconds doing 2 damage. A 4x4 configuration will fire every 2.5 seconds doing 2 damage. The configuration will take on the biggest one it can.
