Massif released a new homebrew NDS game called Lights Off. Goal is to TURN off all lights on the playingfield, which turns out to be not that easy.
Other release notes:
In honor of my new site, here is my very first NDS homebrew game: Lights Off. It is a simple remake of the popular Lights Out game. This version is 6×6 and comes with 150 puzzles.
