Hmm... what I noticed: Dual-gems are generally stronger in strength and faster than pure gems, yet their ability is weaker. While pure gems have better abilities, yet are weaker in strength and are slower. To have a winning strategy, you have to have dual-gems and pure gems. Just keep that in mind.

By the way, this game is fairly decent, always could improve though. Maybe zoom the camera out when you get faster.
