Pre-alpha 1.6

This version has a few more performance improvements. The scoring is also taking shape:

• When you touch green blocks, you earn 200 points for each block in the entire shape.
• Touch red or yellow and you lose up to 800 points per block. (Yes, you can have a negative score if you're not careful.)
• However, if you touch green that is adjacent to red or yellow, you can earn up to 800 points per block.
• Shots clear out red and yellow, but not green. However, if you shoot red or yellow that's adjacent to green, the green is destroyed too. Be careful.
