Okay, I just finished it. And I have to say, I really like the idea, and I can really see the potential here.
The fact that it also gives me mad portal vibes just makes it even better.
Improvements:
- Make the gap between ground and glass bigger so the balls fit better under it.
- Make the movement a bit less floaty.
That being said, I really think you have something on your hands here, and I am interested to see where this goes!
Good job!
