I really enjoy playing games like Puzzle & Dragons and thought this was a fun take on the genre. I think it has a lot of potential and your monster girls are really cute. The arrow effect for lining up orbs is really nice - great job on that. I agree that difficulty-wise it was kind of easy. I think orb-manipulation abilities would be really fun, whether it be spells you can perform yourself or attacks by the enemy. That could potentially make it more strategic as well.
