For a solo developer this is so much already! When you need to insert a sphere with some of the symbols it took me a while to realize I need to use 'w'. I am not sure if I saw that in the controls, or maybe it's for the player to find out :). The idea is so cool, the strange language fits perfectly! The art is amazing, I am a pixel artist myself, I think you did a good job. From what I see you also made the music, but I don't really know anything about composing, so I can just say it sounds nice, simple and what one would expect from such project! Again, for a solo game developer this is amazing, I definitely will be checking out the game in the future, if you decide to keep developing it.
