The ones marked with "Foreseeable" can be checked for if you're really careful.

<ol style="list-style-type:decimal;">[*]Sliding any direction but up at the start leads to a watery grave.

[*]Sliding up immediately as the level starts will kill you. You need to wait for the ball to get out of the way.

[*](Foreseeable) Trying to get a chip behind the recessed walls on either side of the suction boots will get you stuck due to a hidden wall. You can check for this by stepping on the recessed wall that's not below the chip and trying to step up.

[*]Out of the 5 blocks in the X, the 4 on the edges have fire. This is the same pattern of fire as in Leave No Stone Unturned. (Remember that level?) Also, the reason for the walls, and the solid blue wall under the center block, is to prevent block slapping in Lynx.

[*]You can only fill in one water space here. If you don't pick the one with the thief, you'll get stuck with the suction boots on a force slide later on and won't be able to outrun cloned balls.

[*]Once you pass through the recessed wall, if you make a right, you'll run into a hidden wall and then get flattened by a long line of pink balls.

[*]Similarly, going for either red key will get you flattened by that same line of pink balls. There aren't even any red doors in the level

[*](Foreseeable) You can enter the teleport by going left, or up. Go left, and you teleport into a bomb. This can be seen in advance from (19, 30).

[*](Anti-foreseeable) After escaping the stream of cloned balls, you can choose to go onto a force floor slide above you or to your right. You can see that the one to your right leads to water; however, that's a trick. Taking the up slide results in drowning; taking the right slide is safe as a Teeth will clone a block to fill the water in before you reach it.

[*]After hitting the blue button and heading into the blue wall section, failing to clear out the blue walls and extricate the cloned block in time will leave you stuck when the next block clones.

[*](Foreseeable) The balls guarding the chip to the right of the blue wall section are bouncing off hidden walls, so they may rebound onto you unexpectedly if you're not careful. You can observe their bouncing from the blue wall section, though.

[*]In the line of block cloners creating blocks on the ice, the second-to-last button is connected to the cloner one row down instead of the cloner on the same row. If you're running full speed and don't stop, the cloned block will hit you.

[*](Foreseeable) After you get the ice skates and come through the thief, there are 3 blocks in a row and an X of ice spaces above them. If you push the left or center block up, it will rebound off an invisible wall and kill you. Can be checked for by trying to step onto those spaces yourself.

[*]If you run towards the exit and don't stop after hitting the toggle button, then the toggle door next to the exit will close, trapping you as a glider swoops in to end you. You instead have to stay behind on the toggle button or the recessed wall until the glider goes back up, at which point the exit opens for real. This final trap (killing the player just before--or in some cases, just after--the level goal) is called a "Kaizo Trap" after the stage "Special Stage 2" from Kaizo Mario World. Look up ProtonJon's Let's Play of that level for more details, but be warned that the language is very family unfriendly.
