I've found an awesome bug! So, if you want the elite ships but you don't have the legendary key or it's too expensive, load any savegame that has them. I've chosen to take Oozee's savefile. Then you have to die (take the boss World it goes the fastest and use a elite-tier ship) when you have died you load your game again (still in the game over screen) then you should be still equipped with the ship you've played with in the savefile, the other tier5 ships should also be available. Warning: This is a Bug! Probably it happens that in the ships section you'll be able to scroll over farther. Don't do that, the game is going to crash! I hope this helped rate + so everyone can see.
