I gave up and read the source code. It seems like the spell system is not positional like I had assumed, but closer to a string of commands with 2 hexadecimal pairs, like a very basic cpu instruction set. Which is pretty interesting but I spent quite a while looking for the wrong thing. Like at first I assumed latter half of the spell string was for physical properties and first half was size properties, until i made quite a few attempts with that idea only to see i got nonsensical results.
Have you considered changing the spell view so instead of starting with a full set of 16 zeroes, you start with a blank box where it fills up as you type hexadecimals, and with some space between every pair to guide the players in the right direction?
Aside from that, I love the game. 3D physics and a good puzzle is always a plus in my eyes.
Also for some reason, the sun has flickering issues for me
