Wow, very promising game! Congrats! I did the whole thing.
My biggest issue is that it's pretty confusing. I did feel pretty satisfied when I beat a level, and it really felt like *I* found the solution, but I wouldn't really be able to explain how I got to that solution.
The trajectory of the little data bubbles isn't really explained very well, the tutorial says they "never take the same path" or something, but that's not really it. they just alternate between each available path.
My suggestion, make it possible to pause at any point (or slow down time or something) so the player has time to know for sure where each bubble will go, and how to influence that trajectory with nodes.
Also, there's no quick "reset" button, kinda frustrating to know you'll lose but you have to watch the bubbles slooowly take the wrong trajectory.
Finally, congrats on the narrative!
