OK, after reading all the other comments I start to think I must be super exigent with jam games, but I admit I didn't enjoy it too much. But I like the concept, it's more about execution, game design, polishing, etc. Maybe if this was the first grappling game I had seen, I would have enjoyed it more.
I've played several grappling games and in fact, the one I disliked the most had loosy motion. This one hasn't, however I was once sent high into the air to the point I couldn't see the city anymore, and it tooks ages to fall down. Some safety clamping would have helped.
For a spider-man experience you'd need shorter range and an actual pendulum motion, but I see it wasn't the point here, so it's fine. A Zelda hookshot / Attack on Titan motion is cool too, although again a shorter range would force the player to hook from building to building more often. However even with the very long range, you had to control yourself not to overdo it, so why not.
My biggest issue was the vehicles. The first times they just fell out of nowhere on my camera for instant game over. Then I started paying attention to the sky. But once you're out of their zone, there's not much to fear. I'd rather have a classic experience with obstacles along the shortest ways to the delivery zones to make you decide whether you should avoid them or risk it for speedrunning, and/or collectibles along the way so you can high-score by taking certain paths.
There is no metaphor/explanation for the flying vehicles, visuals doesn't seem to match their motion either. Yeah I know, it's just a fancy idea, but even if crazy games like Goat Simulator you *can* understand the crazy logic behind the thing. A kind of surrealism.
For the easter eggs, I suppose this kind of humor is just not my thing... ? I don't know NYC much but I suppose there are some literary jokes you can do about it.
And the music was chaotic and a bit repetitive, I think in this case I would have preferred ambient street sound (that changes when you fly higher maybe?)
Sorry, I intended to just score the game and leave silently because it's not fun criticizing beginners and sometimes pointless bringing rationality to something the author knows is absurd. But I feel like there are too many comments only pointing the good parts, so I decided to bring some balance to feedback (but keeping it constructive).
EDIT: Wait. The karma system means more people comment on your game if you commented a lot on others'. So maybe the sheer amount of comment is just because, as another comment mentioned, you did a good job at reviewing other people's games. So maybe it doesn't really need "balance". Just take it at my personal feedback then.
