"More specifically, would it be okay to have a C/C++ runtime/engine to handle graphics, while using BASIC for in-game scripting and logic?" <--- I think that this is okay. Would you mind disclosing the C/C++ graphic engine and the BASIC scripting language which will be used by you in this jam? Thank you.
I was going to implement c64-like BASIC myself, but it seems like more effort than it's worth when I can embed Lua. I won't be submitting to this game jam, but thanks for replying!
