Rebirth

Once you reach 200000 Gem Value, a hidden passage will be permanently unlocked to you. Jump off the main stairs of the lobby and into the river to find it. There lies the entrance to Insane Mode and a Gem Enchanter who will let you rebirth for the first time.

When you talk to the enchanter, it will show you your current total Gem Value, the required total Gem Value to rebirth and the amount of Crystals you will get if you choose to rebirth.

If you rebirth...

-You keep your Coins, Level, Keys, Crystals, inventory (Pets / Food), current Missions and total Gem Value. Don't worry, nothing much is lost here.

-You lose, however, each type of Gem Value (not the total). It doesn't seem to affect your current Upgrades, but you do need those red, green, blue, yellow and purple gems to level them up further.

-You get a ton of Crystals. First time you rebirth, you'll receive 250 Crystals.

-You get your rebirth in insane mode keys, as well as that many each day. For example: After reaching rebirth five, you will have five insane mode keys, and will get five each day. Note that you cannot hold more than your current rebirth in insane mode keys at any point in time.

When you rebirth, both the requirement and the reward for rebirthing will increase. After rebirthing for the first time with +200k Gem Value and with a reward of 250 Crystals, second rebirth will require +500k total Gem Value and will reward you with 500 Crystals.
