I'm about to upload a bunch of individual level runs, so I thought I'd share some of the "glitches" I use in some of those. I'm kind of hesitant to call them glitches though, they are more like bugs or hitbox quirks, but glitches sounds better so I'll refer to them as that.

There are really only two glitches (three if you count using both at the same time), and both are fairly straight forward.

The first one I am going to call death glitch, and it is probably the easiest to explain and perform. Simply put, dying will stop the timer, but you will still be able to finish the level. This means you have to have a shuriken in the air when you die, and it has to hit the remaining enemies. Upshot is that you end up with the time at which you died, rather than when the last enemy was killed.

A good level to show this off in is World 6 - Level 10. (I was going to make a comparison video, but I got lazy. Just try it yourself, with and without dying, and you'll see there is about a second difference)

The second one abuses a weird property of the electricity robots' hitbox. It turns out that you are able to hit them without having to face them, if you just stand close enough. This doesn't sound super useful, but it can often save you shurikens.

The video below is a good example of how it can be useful.

Lastly you can combine the two. Not entirely sure how this works, but my best guess is that you have to run into the electric robot and then turn around and shoot all on pretty much the same frame as when you die. It's not a big window, but it doesn't really feel quite frame perfect either.

This shows off how it works (without dying you can only get about 2.27 on this level)

Death glitch is almost entirely useless for anything other than IL, since it takes the same amount of time RTA with or without dying. Though it can help to make sure you get three stars, and for 100% it can help make sure you get a worse time when doing the marathons (to skip the "new best" animation). You can technically use the other trick outside of IL, but it's really finicky and precise so I doubt people will.

Hopefully that will help people get better IL times, or at the very least explain why I die so much in my IL videos ^^
