Hi Aonee! Thanks for playing the game and taking the time to give some feedback! The amount of gravity is something we are actively working on this week as well as making the grapple pull the character, I think it will alleviate the feeling of floatyness when you can just grapple around as well!
As for the initial sequence, i hear you, i agree to some degree but like i was saying with a previous comment, we inted to do a cutscene which will hopefully make the black screen feel not as long! I do like the idea of some of the dialogue happening when your in game! I will bring this to the team and maybe try and incorporate some of the last few seconds of the dialogue into the in game when the player has control!
Thanks again for the feedback!
