Tier 12 is the worst. The bigger tier number means the less well you did. So tier 1 is the best. (Unless the creator incorporated 0 tier, on negative tiers)
Maybe some enemies were on the side of the screen, bordering within your line of sight and you forgot about them. There are also enemies with high opacity.
Negative Bonuses: Red X: Engine Damage, slows you. Blue X: Weapon Damage, slows weapon fire time or spread layout. Green X: Ship Damage, your ship gradually takes damage. Purple X: Unaccuracy, the most annoying debuff ever. Makes all your shots go DOWN instead of UP. Yellow X: Gold Loss, second most annoying debuff ever. Steals your gold. Dark X: Darkness. Least annoying debuff. Just makes your ship dark and unable to use warp speed. Orange Z: Cancels current buffs. Pretty annoying in the later levels.
A whitish missle with B on it is Bosskiller missles. Very powerful. A red missle with P on it is Power Missles. It is effective against most enemies, but has little effect against bosses. A Grey missle with just M on it is your standard missle. Pretty uneffective against everything.
A yellow shard with a L on it is Laser. Laser is like a more constant Ultra Fire, and is a special bonus. If you collect Double Fire while in this, you get double fire, except with lasers. Least effective of the 3 special bonuses. G Coins- Give a random amount of money for each level. Dropped by standard enemies. B Coins- Give a larger random amount of money for each level, dropped by bosses. V Coins-Gives 3 million, and is dropped by asteroids without a core.
Bonuses. A green T stands for Tetra Fire. It gives you a spread 6 shot attack. A green P stands for Double Fire. It gives you a slightly spread 4 shot attack. A green crescent with a C on it is Crescent Wave. Or w/e. It is a special bonus. If you grab Tetra fire while having crescent fire on, you get Triple Crescent Fire. This is the best bonus in the game, as it has high damage, spreads, and goes through multiple targets. A shiny gold/orangey missle with a B on it. This gives you the bonus Missle Blast. You fire tons of homing missles. They do not home when your in time slow. This is a special bonus, and if you grab Ultra fire while in Missle Blast, you get Ultra Missle Blast. Like ultra fire, except a little bit stronger and homing. Ultra Fire. Stronger basic attack.
V gold coins grant you 3 million. To get them, you must destroy the asteroid rocks WITHOUT an orange core. They have TONS of life, so you shouldn't do it till you have time slow.
Boss World- If you buy the tool to get you there, know that ALL enemies are bosses. On average, you can get 13 mil from beating it. Use the time slow and the energy replenish together if you ever wish to beat this level easily. Once you go here, you cannot go back to previous levels because it takes you to level 107. Level 107 is the last level.
