Ver 1.3.2 Update: Improved Bullet Visibility

After several months of experimenting and borrowing what I learnt from my other shoot'em up Yellow Trouble, I have finally found a set of color changes that improve enemy bullet visibility across the 10 stages without needing to dull or dim the backgrounds, all while still retaining the yellow-red or blue-red combinations.
This should boost overall survivability, especially for those having a harder time differentiating between two elevations.
