Here's some advice regarding game design: try to avoid wasting the player's time. There's no point in making the player interact with the orbs and then confirm that they want to pick the orbs up. Just walking over them would've been fine. In another example, it's really annoying to have to go back and forth over the same area repeatedly, especially if the context doesn't warrant it. The steps 1. talk to sister, 2. talk to brother, 3. talk to sister, 4. talk to grandfather, 5. talk to sister, 6. talk to grandfather, 7. talk to grandfather again, are already at ridiculous levels of redundancy even without the need to go halfway across a maze between each step.
