Hey thanks for playing! One of my design goals was to keep all the action tied to one button so that my young kids could play this on a keyboard without issue. I found that during the dash section if you release for the first jump out of dash, then press and hold shift for the double jump, you'll land on the next platform already in dash state. It's a pretty nice rhythm once you get used to it. Though I totally agree with your criticism and in a commercial game I would have mapped the actions to separate inputs!
