The crossover of language design/implementation and game development made me assume this was either a Jonathon Blow (Jai, Braid, The Witness) or Bob Nystrom project (Game Programming Patterns, Crafting Interpreters, 'Is There More to Game Architecture than ECS?' [1]).

Either way, given the time constraints and requirements I'm expecting a lot of text adventures and rogue-likes.
