Oh, sorry, I misinterpreted your question. It's Renpy 7 unfortunately...
However, players from my discord server told me there is a web version available here : https://porngameshub.com/dreamland-wanderer
I haven't built that one and I'm not affiliated with the website but it seems to work without issues. Maybe that's the solution to your problem.
Anyway, thanks for playing my game. I'm glad you enjoy it!
