Under rating threshold (hideshow)
A good start. However, fire rate seems underpowered, I put several points into it before I could even see a difference. And reflective is overpowered. If you just keep attack power up to where you occasionally one-shot enemies and always kill them in two shots, put 1 point into piercing, and all the rest into reflective, then you can make the board become just a haze of bullets in which no enemy lives for more than a few seconds. To be equivalent to the others, it should increase the chance of reflecting by, say, 15% for each point you put into it, and each time it reflects should decrease the chance by 50%. That way, once you have put 10 points into reflective, it will always reflect twice, and half the time a third, but that's it. Also, some variety of enemies, including an occasional boss, would be good. But you do have a great start.

Piercing actually does go through the enemy, and hits the next. I noticed that when it is at level 2 it actually hits the first enemy twice, therefore stopping it. Still trying to work that out.

I don't understand.. what's the difference between Attack Power and Piercing Ammo? I figured the Piercing Ammo would pierce through the enemy, not just the armour (as that is what Attack Power is for)

The game is at a slow pace making it a nice challenge maybe you could add a reason for this war and an instruction guide but overall i kinda like it 3/5

Total bullets on screen is about equal to (reflective * time to cross field / average bounce angle) * (attack rate/sec) * (% to hit / penetrative capabilites) * k.

Faster bullets seems like it'd be better, but in truth it lowers the number of bullets on screen, and a high amount of bullets will protect you more than being able to aim.
