Magnetic By Nature is a 2D platformer where you are generally using either attract or repel mechanics. I came across this game on the PAX East show floor, and it really wowed me. I may be one of only a few hundred people who ever played it. There’s a bonus chapter, after the credits, that was kind of bullshit, but the 7 or so hours of gameplay before it was fun, challenging, and unique. Initially available for like $15, it’s now down to $1, and it’s a steal at that price.
