Hi hi, I don't know about Star Ocean battle system but as long as it's real time action then it's possible. For other questions:
- Can we grab ittem and throw like zelda?
Yes, you can grab stuff and throw like Zelda. Please see the trailer for version 1.2.0 :D
- Can we use some grab item and pull in like in zelda?
If you mean a hook then grabbing item is possible but to make a hook visually, it's not supported in the current version. Meaning you can grab other items using other items, but for visual effect it really depends.
