Nintendo has a decent track record in releasing a small number of interesting download-only games, and it'll be aiming to deliver again with Project Mekuru on Nintendo Switch; naturally that's not the final name.
Either locally or online four players run around flipping tiles, also triggering explosions to take out the other players. Items pop up to change your character's abilities, and in principle it looks like a simple spin on the Bomberman concept, albeit with a different approach to dominating territory.
You can see it in action below at the 4 minute 37 second mark.
This is due in the Summer, so it'll be interesting to see how this one turns out.
