I'm coming into this one at a pretty big disadvantage because mouse and keyboard movement in 3d has never felt good to me, and I did struggle a lot in the chase sequence, but cranking up the look sensitivity to almost maximum made a giant (no pun intended) difference. I did really like the sense of speed and scale you managed to achieve in that part though, and found it genuinely exciting even though I wasn't very good at it. I thought the balance of the on foot section, the card battle, and the dialogue scenes worked really well together, and I think your original vision sounds great! A slower, more sneaky exploration phase like you had in mind would be a lot more to my liking, personally, but I did have fun playing the jam version.
I know how frustrating it is to not get to make your jam game into everything you wanted it to be, but you made something playable start to finish, with mechanics that work, and that's a big accomplishment! You did a great job and I hope you give yourself a big pat on the back for it!
