In this game, every single letter you do does chip damage, while typing out the full word does a lot more damage. If you misspell a word, you have to go back to the start of the word. When you get hit multiple times in succession, you become frozen and can't type, which often forces you to misspell words. This is known as Hitstun Locking. You become forced into it and can't attack when hit multiple times, luckily, you can also do this to your opponent as well.

"How can I type that fast?" I'm glad you asked! This game suffers from a fatal flaw of what I call, the Initial Letter Exploit. As mentioned, typing a letter deals chip damage, but missing a letter resets the word back to the first letter. If you mash (or even just hold down) the first letter of the word, you start dealing chip damage in a massive amount. Typically, enough to Hitstun Lock your opponent. I've seen some people like me and a few others have INSANELY good results with ILE while others still struggle facing against Elmo. Honestly, I can't figure out why this is. I think it might have something to do with browser versus browser or even a computer problem? I don't think I'll ever quite figure it out.

Well, there is all you need to know to start speedrunning Sesame Street Fighter. Good luck and happy mashing!
