I really love the concept here! It's super unique and I could see it becoming a genre in and of itself. I think the game could do with a tutorial and/or for the loss+restart process to be a bit quicker so you can jump right back in after a failure. I think the different nodes being different beats is just really cool and while I do like how difficult it is, I think it could just be a bit less punishing on reading things in the moment (maybe a pause button that still allows for tool tips and whatnot)
Awesome game! Thanks for the experience
