Since Adobe Flash will be gone in 2020 it will make it hard for us to use Kisekae. But never fear there is a downloadable version of Kisekae.
Here is a link to the downloadable version of Kisekae https://enty.jp/posts/76546 But before you download it you need to create an account on the site you get the downloadable version of Kisekae from.
You download it anytime you want. But you first need Adobe Air and it's free to download. https://get.adobe.com/air/
So for all Kisekae users I'm getting you ready for when we can no longer use kisekae it's site.
Also MEGAF1SH told me before that he asked the creator of Kisekae that the Downloadable version will still be getting updates.
