Nice design, animations are a bit overkill for me and take too long. If they were cut in half you would have a way better experience.
yay, looks awesome! I'm glad to hear that this kinda cool events are happening in Poland and not only in Warsaw! Good luck!
By the way, on the Speakers page - Martyna and Gosia has funny "shutterstock" watermarks - is that in purpose?
This is beautiful, really great colours and typography.
The interactions are pretty heavy, but considering the audience I think the focus on over-the-top animation is fine - to show off and have fun with the format.
