Such a cute and pleasant game to play — I love Bob!
My only small critiques would be that hearing the footstep SFX while the character is in the air feels a bit off, and the grappling hook could use a bit more “juice.” Maybe making it snappier, using a sharper sound effect, or even adding some camera shake could help give it more impact.
I really enjoyed playing through to the end — now I’m wondering what ending I would’ve gotten if I had been a bit greedier!
Really great job overall — super creative and well executed.
