This was a cool little game with a great thematic setting, but I often found it pretty difficult to control. The minimalist pixel art style, surprising futuristic neo-Japan setting, and well themed abilities all tied the game together really well. I had a real frustrating time with the grapple hook. At first I thought it was just inconsistently buggy, but then I realized that you cannot press a horizontal movement key before pressing jump if you want to do a double jump. This was really difficult to do, and a bit counterintuitive. I would recommend iterating on these controls and timing to make the grapple jump feel more natural. I would also recommend adding more player feedback to combat, including enemy knockback on hit, and both auditory and visual feedback on the player taking damage. I feel that if you focus on polishing these two main pieces, you will greatly improve the feel of the game. Good work!
