If you keep developing it as now, do whatever is more comfortable for you; if you feel that delivering days piecemeal compromises your vision, go day by day. Personally I'll enjoy seeing whatever content you are ready to show as soon as you can show it but what matters most is what you feel is better.
If you are going to transition to a paid format down the line though (e.g. Patreon), you should find a way so you can deliver at least some content in each payment period.
