Slinki (itch) (Titan Forged Games, crushy)

Slinki is a hard-as-nails 2.5D action-platformer where your own prosthetic arm is the ultimate multipurpose weapon: Use it as a bladed boomerang to control the population of mutated critters, pull levers towards you to get through puzzles and zip-line across grappling surfaces or traverse the landscape by having you return to it instead. We had a Linux version in the past but I have no Linux machine to test with right now. Send me a message if youd like to volunteer :)
