Yes, we would encourage you to submit your pitch for the game design challenge.
We will be able to figure out how best to proceed if you are selected as a Finalist. At that time it might be helpful to share more details about your language, compiler, and engine with us so that we could become familiar with them.
One nice aspect of our game design challenge is that several of the judges are usually professors teaching game design or running their university's game design labs.
Feel free to reach out with any other questions. We look forward to seeing your game pitch -- this year's is an especially challenging challenge!
