Thank you so much for the comment on the music. I get task paralysis when composing/producing, that only time pressure forces me to overcome and worry less about it. But I ended up having fun with this one, and I'm really glad you enjoyed it!
Your expectations for the movement are well founded. I noticed in my IRL guinea pigs playtesters (my poor family) that they were trying similar maneuvers. To be honest, due to running low on time, the scrolling is entirely an illusion, one that the mercury doesn't adhere to. Under the hood it's more like a platformer with Zelda-like hazards. I'm doing some post-jam improvements and the movement mechanics are going to get major attention.
Thanks again for your thoughtful feedback.
