Thank you for your comments! I think we spent a little too long working on the concept/story than we did on actually making the game, but I'm glad you picked up on it. Originally the team wanted to make both old and young player to have equal portion of gameplay. With the time constraint, they were only able to focus more on the young player. But I am glad you were able to discover the upgrades for the Oldman, I know that part wasn't super obvious!
We also weren't sure if we would have boss music, but Jason totally came though with it last minute. :) About that one song getting a little repetitive. Maybe we can beg him for a longer version or maybe just another variation of the theme for the non-combat area. That's definitely not something that was super obvious to the team as they are so use to beating the game quick.
I'll let other team member comment on your feedback on the movement . :) Mini-map is a great idea and I think very likely something that would be implement if we work on this game more.
