ahh feels great that you wanted to go back, hah! usually jam games can be "one-and-done" so.
you're totally right about the clear indicator for when you can't take out sword/shield yet. that's something i should've polished into it for sure! no definite plans to continue the project, yet, BUT, i have 5 pages of lore and the world/levels have been mostly thought out to be 4x bigger game... so it's not a definite NO either!
