This is my home account while chaitanya127793 is my student account. Scratch told me that student accounts are temporary so I made a new account, this one with the same projects and more. If there are any ways to improve them drop them in the comments. I made a glitched version check out chaitanya1127793 jump to escape the dragon remixis. If you want to remix ask on my profile.
