Well done for shipping! I'm really impressed by the tool - it's intuitive and like a very light-weight After Effects.

I think just re-designing the landing page would make a huge difference, very quickly. I think currently it lets down what is a well-crafted design / animation tool. Get rid of the white and teal, and the default system fonts. The looom site is a lovely example (https://www.iorama.studio/looom).
