I think 2D fits better with the original version of the game - While 3D would be fun, it'd give a completely different feel to the game which might make it feel far removed from the current experience. It might make it more difficult to work with, but I think it definitely is worth the trouble.
Of course, the final decision is ultimately up to you. I just think it'd be nice to keep the original feel of the game there in a Feraline remake.
This is true! I'm leaning towards 2D for the remake, and I will continue practicing 3D. Later into the future, I can release a 3D version of Feraline when I feel it's up to standards.
I do plan to start working on a remake soon-ish, but I can't know how long it will be until it's released. I do hope to have the previously mentioned anthro game released soon, as it's mostly finished and just waiting for the artist to have time to finish the art for it.
