Totem Destroyer
Everyone I know who tips me off for great Flash games has been nagging me to play Totem Destroyer. I did, and you know, it just wasn't for me. I finished it quite quickly, and never really felt the love. However, wiser people did, so I pass it on to you.
It's from the reliable Armor Games, made by Gabriel Ochsenhofer, and using Erin Catto's Box2D physics engine, and involves removing blocks from a wobbly tower such that a golden idol doesn't hit the ground. Remove the required number of blocks and win the level. For me it felt more about quick luck than any great application of skill in a world of physics. But perhaps you will enthuse - play it in your browser here.
