The gameplay was really fun. The grappling hook mechanic was creative, and the overall vibe of the environment was suspenseful. I also enjoyed the environment hazards. It added another level of challenge and thought to what I was doing, so kudos! I think one thing that could shine here is an addition of footsteps, something getting dragged on metal, a couple loud bangs in the distance, or anything similar to that. The game sets the scene so well and I think that could push it to the next level. I would love to see this game continue being worked on. You've got a great idea here!
