OK, initial feedback: you need to work on your colours and contrasts. Disabled Previous button isn’t clearly disabled, placeholder value looks almost the same as an actual value, focus indicator is too subtle. I reckon these things are noticeably harder to get right on dark than on light colour schemes.

Also keyboard navigation is poor: when you shift to a new page, you should probably focus the first field; or at the very least reset focus to the start of the document so that when the user presses Tab after having clicked the Next button they get to the first field, not the footer “Powered by Ikiform” link. (This doesn’t affect pressing Enter from one of the inputs—when they disappear, focus shifts back to the top.)

But I’m pleased to say that it’s nothing like Typeform. I strongly recommend ditching any comparison with it, you’re doing things sanely, unlike their experience.

It’s a nice form. On iOS when I hit next it didn’t pop me up to the beginning of the next page. Agree with the sibling that it would be nice to get focus on that next obvious step.

The name fields have a minimum length of two characters. There are people with single character names.
