If this can become a reality, we could "push" the possibilities with puzzles even further!
Examples of applications:
- You cannot reach the top of a cliff without its Delta power, BUT you could roll it elsewhere to reach slightly higher elevations that were once out of your reach.
- SOMEBODY IS TRAPPED BEHIND BARS! EVEN WORSE, "THEY" STOLE THE POWER FROM THE NEARBY DELTA ORB. What to do, what to do... OH! Let's find a way to restore the ROLLING Delta Orb's power! THEN, we could remove some tiles to make an escape route--WAIT! What if we cannot do that? What if the ground is unchangeable? ... Maybe I could reach a higher place instead, to look for a switch? GOOD IDEA!
