This is a really well-made game overall. I would point out three things;
1. Grappling and hitting those electric grapple guys are hard enough without them also being electrified every five seconds. The electric platforms were *mostly* okay, but every other grapple room felt trolly.
2. In one of the already-more-frustrating rooms with a grapple-those-guys mechanic you can softlock after completing the room (respawning or leaving and re-entering the room doesn't spawn any mercy platform or respawn the enemies.)
3. This is a mechanically solid game and it's good to have to think about placement and even the directionality of an attack; it's very engaging overall, and kudos for that.
I'd love to play more of this if you're planning on a post-jam release.
