While fighting the steam train (saving earth dragon)destroy all pink crystals die, repeat until everything is upgraded.
When u die, u go back to the start of the lvl. ok so we all know that.
But... if u do the lvl except for the last enemy/enemies, die on them, then go back to the start of the lvl. every time u go back to the start of the lvl get all of the pink crystals and get all of the upgrades in the game.
I worked this out after i completed the game normally and i noticed u can defeat the enemies quicker with every skill.
PS. when u complete the game, u keep all the skills u unlocked if u start again!
