1. Design language of the forms feels too much like Typeform, you're a talented designer: differentiate the design to establish your own identity. If the forms look like Typeform, form-fillers are not going to investigate what form software it is and use it -- which was a big part of why Typeform grew.
2. The name is terrible. Blocks? The name sounds like you decided on it for a different project (some sort of component framework using Markdown?) and then reused it for this. The domain forms.md is available to register. Anything that include "form" in the name would be a significant improvement.
