Yes, it is. It was made for the GMTK Game Jam 2022. Despite its inferiority in processing and myriad limitations, I find it a useful engine for getting my ideas out quickly in a format I've coded in for years, and more is possible in it than one might think.
Oh! That's cool! I use scratch to make my games too. It's simple and quickly to use, idk why is it so underestimaded, of course the vanilla version has a lot of limitations, but on the scratch mods, like turbowarp and penguinmod, these limitations are almost non-existent
