It was an amazing game i didn't expect so late in the handheld's life.
The framerate never bothered me, it's clear when a game has been designed for its running framerate, and Samus Returns is one of them and plays amazingly.
Only bad part of the game for me were the Metroid fights, MS did their best for shaking them up by modifying the arenas but there's so much you can do when the bosses are the same.
But the game itself is great, even if It departs from the original too much, i don't care, Mercury Steam showed what they were able to do.
Now that Dread is being successful, i hope it's re-released on Switch, but not because the 3DS is outdated, but because more people needs to enjoy it.
Come on Nintendo, show your users the Dread prototype.
