The first issue that I see is that there is a 'Credits' button that doesn't give credit to the people who actually made the various decker examples and resources that you've combined into this deck.
I suspect you don't have permission to republish these works but even if you did have that permission I would consider proper attribution and a link to the origins of each component to be mandatory. It's irresponsible to make yourself appear to be the only source of a resource you're unable to maintain.
Internet Janitor made the majority of the components of this, though other credits should go to woodring and to tangentstorm. (And to Millie Squilly and I , too. Some of our artwork has been copied in as well...)
My main feedback is that you should get proper permission to do this kind of project.
My secondary feedback is that you should take some time to understand the things you've copied in their original context because Millie is correct, many things are broken because they're missing some component or they've been connected together incorrectly.
Have you made things yourself in Decker? It would genuinely be more exciting to see what you've made yourself.
