LukeZGD has ported visual novel Doki Doki Literature Club! to the Nintendo 2DS/3DS:

DDLC-3DS

A Doki Doki Literature Club port for the 3DS! Programmed in Lua, running under the LovePotion framework.

This port is unofficial and is not affiliated with Team Salvato. Please support the official game. You can download Doki Doki Literature Club at: http://ddlc.moe

This was intended to be only for 3DS systems, but it is also working on other platforms that support LÖVE or LovePotion. It will still have 2 screens, though.

v0.3.0 Changes:

Now playable from start to finish! (Acts 1 to 4)
Partial Switch compatibility (it was broken in 0.2.x, and I only tested a bit in yuzu)
Other minor changes and improvements

Known issues:

(3DS) There still may be random crashes... Save often!
