Just tried the Spideriiny demo. WOW!
This is the best swinging simulator I've tried. I've played the official Spiderman game, Windlands 2 and Unbreakable Gumball. Maybe I just didn't get the hang of the others, but this felt so good.
Swinging is not exactly intuitive, but once you get it, it's so much fun. The "rope" retraction is key for building momentum, but it's not like windlands where you can just reel yourself in. You actually need to swing to get moving.
Rope placement, timing, length and left/right balance are all important so you can keep going in the right direction and not slam into a building.
I wish there was more of a game here, maybe just a checkpoint race and consequences like dying if you run into something with too much speed.
