#Level 12 In the world record run, DeamLinX Opens the top right chest first, then the left chest, then the bottom right chest. It's faster to open the left chest first, then top right, then bottom right. After getting the sword, jump over the ledge to get more falling speed, and you can hit the wall and immediately double back to get to the chest. Then get the top chest, and do another jump down to hit the wall and get the bottom chest. (If I'm not explaining well I can get a video) #Level 13 After getting the sword, you have to run down some stairs. When you get to the bottom, there's a small ledge that you normally have to walk on before you hit the wall and turn around. You can hit the side of this, saving about a second. Just like in level 12, you have to jump to get more falling speed. Jump over the last two ledges in the stairs and you can do it.

I also found a minor strat for level 2: The world record places the bed facing right on the platform with the first chest; it's faster to place it facing left (right-click)

Wow, i thought these two strats are impossible, but now I rechecked it and got good time, I also found second minor skip in level two. Instead of hitting two walls at the start, you need to jump from bed to this hole. You will get enough speed to not hit them. But it's around pixel perfect.

In pixel perfect I mean correctly placing bed and getting chest at the same time
