Astraware has released a new game called
Tantric (trial available, purchase the game for $17.95).
"Tantric is the 'all singing all dancing' update to the classic puzzler that was Abysma. It sports a stylish new look, and a stunning musical soundtrack.
Simply plug the gaps with existing pieces to prevent the descending bar from travelling over any spaces. Tantric starts off fairly calmly but as the levels increase so does the number and complexity of the shapes so you will soon find yourself racing to fill the gaps before the bar gets the better of you."
