Thanks! We've been working on Jetstream (http://jetstreamgame.com/) as a follow up with the same core mechanics but fleshed out a bit more. Maybe that scratches your itch?
I've fixed the scrolling bug before, but unfortunately the ever-changing web standards means that it constantly needs a new fix and I don't have the capacity right now to look into that. Sorry! Hopefully playing in fullscreen or with the itch app is better :)
