Visually really great, had some issues with collisions but still pretty solid.
The central mechanic is cool and works really well but doesn't feel connected to being 'out of control' to me, personally.
The sword feels like a dual-purpose tool, and I don't see why one of its intended uses would be 'out of control'. The explanation both contradicts and reinforces this as well, it describes activating the switches as gaining control, but then also implies that having your weapon available as being in control.
Making the environmental objects somewhat controllable instead of on/off (maybe this does happen in a later level?) or changing how the character moves with and without the sword could help in that regard.
Either way, this is mostly nitpicking - congrats on the submission! Cheers
