This is incredible, what's the license of the work? A derivative of this (using a forth-like with only recursion) would be perfect for the current game project where I'm lacking a visual representation of spells (both written and animated). Mystical provides the missing piece of the puzzle of how users could write their own spells in a structured way within the game and still feel as if it's part of the game world with the same kind of thinking as in regular programming.
Noita has similar want building system for constructing spells in a wand in programmatic way with repeats, multiplies, duplicating and such:
