No RegretsG 10

There is a very easy-to-exploit glitch in this game which allows you to breeze through the entire game. Every time you exist and start the game again, you are given 3 additional revive tokens. You can do this again and again, back-to-back, infinitely. Farm all the revive tokens you need (I recommend at least 20 for the later levels), and bring yourself back to life whenever you need. Never worry about losing eyes again. This will be especially helpful in your hunt for the black egg/hammer and a Rammstein.

No Regrets G10:
Complete the entire Regret Layer.

For this achievement, you must complete the Regret layer. This is the 11th layer and requires a total of 840 eyes for completion. I highly suggest having an extra heart buff, plenty of powers, and a few revive tokens as portions of this level (and every level following) can be very difficult. If you've reached 840 eyes but still have a while before a pit stop, I suggest skipping enemies and trying to go through the level as quickly as possible to reach the next pit stop.

**UPDATE**

A level select function has been added to the Windows 8 version similar to the Windows Phone version. Now you can select the 11th layer in the Pause --> Restart from Layer Menu. However, you should get this achievement after completing the 11th layer so there shouldn't be a reason to use the level select.
