The time button gives you an extra hour, heals you for 1, and then multiplies the cost of the exit door and itself by 10. 

The creation of perks in the shop works like so:

1. A pool of perks is created to draw from. Every rare goes into the pool once, every uncommon goes in 3 times, every common goes in 7 times. 
2. The game then picks three from this list (they are not allowed to be the same, and they are not allowed to be the same as whatever last showed up in the shop if you're rerolling). 
3. There is a 1% chance for a perk to be attached. The attached perk is selected the same way as the initial cards are.
4. There is a 2% chance that one of the perks will be on sale, which halves its cost in the shop.

I will get back to you soon with the list of perks.
