Tiled is such an important tool for 2D game developers that I’d like to think it would be easily and fully funded.
My homepage for Tiled2Unity gets decent traffic so I added a small plea for Tiled’s case there as well.
I’ll be having additionaly Tiled2Unity tutorials over the next couple of weeks and I’ll use that platform as well to point developers this way. At the very least I think that $500 milestone can be met soon.
Have you ever thought of reaching out to successful developers to ask for a plug and/or contribution? I can imagine the developers behind Shovel Knight and Titan Souls would be happy to help given that Tiled was an important (and free!) tool for them.
