A frothing geyser of black vapor lies somewhere in every level, and it's up to you to send the shivering little protagonist tumbling into the miasma. The game's kind enough to tuck a decidedly useful trick up your sleeve: white objects can be disintegrated with but a single click of the mouse.

The title sounds like the name of a top-secret Cold War superweapon, or perhaps a very specialized brand of bleach, but Red Remover has nothing to do with either Soviets or stains. Instead, this latest offering from Gaz charges you with the task of removing all of the melancholy red blocks in a level while keeping all the exuberant greens.

Redstar Fall is back, with 20 more levels of physics puzzle mayhem. Blast away the tower of bricks one by one, to bring the red star to rest on solid ground. These new "Pro" levels are tough and finicky as a dried-up alley cat, so practice up on the first game before you tackle them.

Redstar Fall is a short but wonderfully executed and atmospheric entry in the physics-based stacking/unstacking genre. you begin each level with a pile of oddly-shaped blocks sitting on an island floating in the sky. Click on a block and it vanishes, allowing everything above to shift with the pull of gravity. Your goal is to ease the red star down so it comes to rest on the island.

Following the success of the first game in the series, Totem Destroyer 2 is bigger and better. In each level you must bomb all of the destructible blocks, without allowing the golden idol(s) to touch the ground. It's a beautifully executed follow-up to the excellent original, and it should not be missed. There's way more levels, new types of blocks, new types of idols, and even a level editor!

Totem Destroyer is, to say the least, an ironic name for this little jewel of a puzzler, considering that the very last thing you want to do is destroy the totem. The goal of each level is to instead retrieve the tiny golden little idol unharmed. Keeping you from your prize is the precariously stacked structure upon which its perched. Your goal is to selectively destroy the required number of blocks for each stage without letting the totem touch the ground.
