I'm so glad you brought this game back for this jam - and did a wonderful job expanding upon the 3D platforming mechanics from the last submission!
Each member felt relatively smooth to use, aside from couple hiccups that have already been mentioned like grapple feedback and getting stuck as Ina, and swapping between abilities when necessary wasn't super clunky.
Otherwise I would say story might be something to iron out, but it looks like we're still gathering the avengers right now anyways, so that can wait a little bit longer - and I only bring up story since this is a continuation of the first game.
This is the first multi-jam project that I've seen, so I'm looking forward to seeing if you can continue it into any subsequent jams, though it looks like you might already have that on lock, and seeing how it grows, great work!
