This was amazing! This game gave me a peak into the strange world of "how my brain learns things", on a whole other level than normal learning experiences. It would be too abstract to describe just like that, but i feel like this "mathematical experiment" has given me food for existential thought even.
I like how, even though i never got a good sence for the space around my character, i still learned some tactics for specific situations, that allowed me to play the game in a somewhat controlled fassion.
I have no clue on how you would make a bigger game out of this... to me the explorative existential joy of feeling my brain adapt to a "mode of being" that i had previously thought unimaginable is allready acchieved...
Maybe if you share my "explorative existential joy", and understand the appeal, you could expand the game in a more artistic direction. Pursuing this "explorative existential joy", i could see you adding some text parts in between challenges, some of wich could have different natures, for example more fast and/or precise maneuvering. Maybe a different setting and art style.
Or just leave it like this. It was a great experience for me to play it anyways, and i think ill come back to it! Never got past the part where it's just a ton of those blue guys.
