Good use of visual effects like particles and screen shake, fun concept that I could definitely imagine playing on a mobile device and having a lot of fun!
Two pieces of critical feedback would be: it gets quite confusing when there are many nodes in a cluster, I often didn't know which way the hexagon would travel next. Two ways to help with that visually would be to disable every other node's activation circle visibility until that one is the next one or two nodes in line, another way would be to have the next node's circle be bright and colorful to grab more attention.
The second problem I had was with the sfx when successfully boosting as there is a short but sharp sound that would hurt my ears, resulting in me having to lower the sfx volume, which is unfortunate because every other sound in the game fit rather well. Having the option to control volume levels btw was very appreciated! Awesome work overall!
