Nintendo don't currently support HTML5 games on Switch... You should ask Nintendo for HTML5 games support, since if they add that we can add support directly.
So, the short answer is:
We do not plan to do anything for this, the Construct will not support Nintendo Switch. Never. Ask Nintendo for this.
And this answer is very disappointing. Of course, Nintendo will not change a successful console, for the sake of a small engine. I understand that you are a small team, but you are making an engine for indie developers and are not going to support the most popular indie game console? Seriously?
This is the same when I read that the Construct, which 2D engine only, still does not support animation with deformation mesh.
No wonder people choose a different engine. You do not even promise that features will appear someday in the future. Features that are just basic needs in other engines.
I apologize for the tone.
I really like the Construct.
but these two missing features make me think not to develop a game project on it.
