Fun puzzle game! The visuals are simple yet pack a lot of juice through the effective use of particle effects, animated text and shaders. The music is very relaxing to listen to and having it slow down during programming is a very nice touch. The sound effects make the game responsive, but they can be a bit loud at times. The programming mechanic is solidly implemented and I'm glad that not everything is tied to the loop as being able to move freely made the game more enjoyable, though having an indicator showing where the programming loop begins would be nice to have as it could provide extra clarity to the player.
Overall, very well done! 👍
