Have you ever heard of The Big Adventure Of Owata’s Life?
If you haven’t, it’s the flash game that inspired I Wanna Be The Guy and Syobon Action (Cat Mario)
Well, I made a pseudo-sequel to it that contains levels based on IWBTG and Syobon Action (and Touhou too)
Here’s the link to it:

I agree with one of the commenters in itch that it would be good if you made an html build. You said you tried and it didn’t save. Have you considered trying again? Or seeing if you can save one of the example games as a web game to see where the problem might be? I think your audience will increase if you make it easy for people to play your game.
