When I downloaded the windows zip, SDL2.DLL wasn't in the package at all. I grabbed it from the site Terrapin suggested, and that fixed it.
I was having a issue launching as well and i did the same and it fixed the issue
I'm really sorry!! In my rush of getting a bugfixed version up I packaged it wrongly and missed out SDL2.dll.
I've fixed it now for people in future, thanks for letting me know guys! ;-; I hope you enjoyed the game regardless
