Always collect the flames as fast as possible after the level, no matter what. Timing starts when pressing play and ends when you the green screen appears.

In the first stage: Just hold d and use the mouse to press right, take down the tree, when nearing the end just jump over the gap, and then fall into the pit and jump from the left side to the ladder place, then proceed to make the jump boost potion, climb the ladder in the last few frames so that when the new level starts, you're still climbing up the ladder.

In the second stage: Press right to get glitched out of the wall on the left side, then go left, pick up the pickaxe, and do the level normally. At the end, go to the top left platform and just walk into the left wall, this will kill a future zombie in the third level.

In the third stage: Just climb to the third platform and then take around 2 to 3 steps back, press d and to the right with the mouse and jump last second. Then take the sword and kill the upper zombie, jump to the lower zombie and stand in the panda, while having your sword slightly outside the map.

In the fourth stage: Just do the level normally, nothing else really. The first cow will be gone. Press in the direction your moving with your mouse for extra speed.

In the fifth stage: Do the tree thing, pull the lever and jump on the platform, place yourself to the right of the platform so that you glitch into the wall when it goes up, then proceed to press left, in the sand block, just go apeshit on that and it will transform into tnt.
