lol I actually really like this. It’s simple, but with a little UI touchup I could see this becoming a popular little tool used to create short & fun web games with. Like Flickgame 2.0
Maybe add some effect options? Like the ability to change hues & saturations on images, or playing & stopping gifs. HTML images are pretty deep in their abilities, so targetting them was a smart move to allow for more options if you decide to continue this.
Anyways, fun little tool. Nice job!
