Easy "Sequence Breaker" Achievement
To successfully sequence break and reach the generators in each of the two earlier caves, you will need three dynamite and enough health to withstand at least two dynamite blasts. In Cave 1-1, go around to the left side. Locate the ledge on the right wall found directly below the top area you are trying to reach. Throw a dynamite downward. Hold [Left] just as it explodes. You must curve around the edge of the top platform in mid-flight, then hold [Right] again to land on the top platform. Continue through the generator cave. You must use a steam jump at the vertical laser section. Stand on the edge of one of the laser-targeted blocks. If positioned correctly, you will not take damage. Go back and heal. In Cave 2-3, go to the gap below the vertical opening then dynamite jump directly up, collecting the minerals on the right if desired. In the generator area, use a second dynamite jump after the uranium hallway and the Shiners. Make sure you have enough health for that section. "Sequence Breaker" will be earned after you break both generators.
Long-Range Pickaxe
If you stand on the very edge of a tile (meaning moving any farther would make you fall of the tile), you can hit a tile that's across from you (assuming there's a 1-tile gap). This is very useful for getting ores just out of reach before you've obtained the Sucker Punch.
