Ring Man's Stage: Space Simulator
Slide across the 'rainbow',Jump and shoot the cannon(it can only shoot at 3 different angles) and climb the ladder. get the next 2 canons and jump on the middle of the next 2 rainbows, climbing the ladder again. Next, 2 planets that both look like saturn and move like the Telys from mega man 2 come floating towards you (the good thing is that their HP is only 1, so no need to worry). Shoot them and continue on. The next screen is a chalenge, 2 cannons high above you, and sevral short rainbows in between(did i mention that these disappear? i don't think so). slide across the rainbows, and get the cannon out of your way. climb another ladder and continue on. now cross this next rainbow and prepare to get 'gamers thumb'. its... a giant hippo?! anyways, shoot the blocks its standing on to lower it, so you can shoot it more easly, but the blocks regenerate, and the hippo will spit homing misles at you. get rid of it and move on. Ignore the new type of Spines below the rainbows, shoot the planets, and-oh no! there's a pair of rainbows above some spikes! anyways, jump as far away from the begining of the rainbow as you can, and slide the rest of the way over. jump down the pit and another sub-boss is waiting for you. its a bunch of rings with closed eyes. WTF? so, if have Bright man's weapon, use it as soon as the rings shoot outwards, and give him heck! When he dies, the thing he was standing on blows up. drop down, but dont charge your buster, you wont need to. Why? because it's another @$^%#@# giant hippo!!* so just use the same strategy as before, or 2 other options: now charge your mega buster or use rush coil to get edie's item, then move out. It only takes a charge shot to get rid of the next 4 enimies, so dont panic;
 * 1) 1 use rain flush over and over again, or #2 use bright man's weapon.**
