To answer your question:
The rules on https://itch.io/jam/gmtk-2020 say:
- Your game cannot require additional software such as an emulator, or a game like Super Mario Maker 2, Roblox, or Dreams.
So it should be self-contained.
Even if it were allowed, your game is then much less accessible and few people will probably download extra software.
Nevertheless, the screenshots look cool! :)
