The princess was finally found!
My experience with the game was funny as after multiple tries I eventually reached the 3rd level using only the hook and my experience with Umihara Kawaze before realising you could press the Jump button more than once.
I had a lot of fun playing the game, the controls feel good including the hook which is great. The heroine looks cool, I like the diverse environments (the last one looks very nice) and the game offers the perfect difficulty for the jam to me.
My only caveat would be that I often felt the screen was centered too high (with the foot of the character on the bottom of the screen basically) which is not ideal when you're descending or need to jump to a platform which is lower than you current one.
Getting back at least 4 lives when entering a new level is cool but I think you could still bring the extras from a previous level when you have more.
Very cool game!
