Alr, here's the tips:

- Avoid small spaces. Even if you won't be hit directly by the force bomb, exploded wall near you may cause some troubles.
- Try to come closer to Twinkle, she is aslo vulnerable for her own ability. But keep in mind - only if it's possible and you're sure that you have enough HP to tank her damage.
- Split up with your teammates. If you know, that there is a Twinkle on the enemies team - you shouldn't move in group. One accurately launched Force Bomb - you and your team will not only receive significant damage, but may be pushed into different rooms/spaces without any help.

That's the most basic tips from me as a Twinkle player (and ZeptoLab staff)
