Balance update: what's new for Ram, Phantom, Electra and more. Tank64

We updated the balance. What's new: Ram: restores health for every wall it smashes. Phantom: invulnerable for 6 seconds after respawn instead of 3, and can shoot right away. Reaper: lifesteal grows with upgrades, every level heals more. Spark: at max upgrade, bonuses last twice as long as normal. Electra: the bullet flies faster, and the electroshock now stacks: every hit in a row slows the enemy more. Ricochet: hits harder after bouncing off a wall and no longer loses damage over distance. Laser: reaches one screen, not across the whole map. Also, in battle you now see how long a bonus has left, and a green number pops up over your tank when it heals.
