I use RenPy, GameMaker Studio 2 and plenty of blood, sweat and tears!
The RenPy games are mostly on Itch,io (not HTML5), but the GML ones are available to play right off my site if you click on their banners!
These are just goofing around experiments, I am not a pro. So try not to judge me too harshly...
If they stop working, reload page and hope to not to break it again. Make sure your browser settings are normal too. I'll work on fixing them when I can but for now, many of these break after the end of the first stage.
Most of these are downloadable/playable off of my itch.io.
