Not in the official catalog (https://play.date/games/search/?q=&sort=rank&category=apps&submit=Search) but there are 3rd party apps on itch.io & elsewhere that have been developed with some web functionality.
In exchange for purchase, the listing indicates I would be able to download "BEAT LIGHT.pdx 46 MB", but this is in fact an html file & not a .pdx that I would be able to sideload if it were in the format listed.
I was eager to try this otherwise aesthetically appealing game out on device & the images provided lead me to believe that the monochrome version could be played on a playdate~
