It's not very hard, but for anyone wondering (and because it's the most used trick), here's a guide on how to cube jump. Step 1. Get cubes, Any% NG will have you getting to stage 2 before you use these. Any% NG+ will have you using this trick right off the bat. Step 2. Angle your camera down slightly, it's a little finicky but once you find a angle that works, stick with it. Step 3. Here's where it gets tricky. To cube jump, jump into the air, move forward* look at the angle from step 2, then shoot the cube out, and jump again. To do it optimally, you'll want to suck the cube back up right after jumping, so you can jump infinitely.

The combo looks something like this. Look at angle, jump while moving forward*, drop cube, jump, pick cube up, drop cube, jump, pick back up, etc.

• • There are two points in the run where you do NOT move forward while cube jumping. These are, 1: Beginning of stage 2, where you back up into the button, and 2: In stage 4, in the final room, as you drop down to hit the third button. What you need to do here is drop the cube directly below you, and because you'll be falling faster than it, you'll land on it. Once you land on it, jump, and pick the cube up. The combo for these two parts looks something like this. Look straight down, shoot cube, land on cube, jump, suck cube back up (sucking cubes up during these jump is much harder than normal cube jumps, however for stage 2 sucking it back up is not necessary, and it depends on how many bodies you have left by the jump in stage 4).

Please note there is a weird jump you can do off the cubes (Which I call a cube slide jump). The only difference is that, you walk midair. Yes it's crazy but let me explain. When this happens (I have yet to find a consistent way to do them), you'll be doing the walking animation midair, and you'll have walking speed as well, rather than air speed (walking speed is faster). If you continue to hold space, once you let go, you'll jump, yes this includes being in midair as well, so if necessary you can jump midair, and go back to air speed (although it's more recommended to just fall to the ground because otherwise you'll revert back to air speed, and it'll last longer because you're in the air longer).
