I’m excited to share!

The project has become quite big, but I’m glad to reach the point where I can release it

If you want to see the development process, here is a Twitter thread with GIFs:

Also I should to ask the help with testing the animation runtime, there is a lot of cases and it become very time consuming to check everything. Thanks!

Let’s make something amazing together :wink:


You can thank @Insality using one of the following services:


Старую версию только не удаляйте пожалуйста. Она нормально работает. Спасибо.
Я по старинке беру лишь несколько строчек из готового результата. Просто чем больше всяких зависимостей и библиотек - больше тормозов.
