Trine 2 developer Frozenbyte kicked off a "Huge Seal" promotion, joining up with more than two dozen other indie developers to offer discounts on 35 PC and Mac games. To take advantage of the "build your own indie sale," buyers need to log in to the sale's site with their Steam accounts to access five coupons from the list of participating games, seen after the break. Among the indie games on sale are Mark of the Ninja ($7.50), Monaco: What's Yours is Mine ($6.60), FTL: Faster than Light ($5.00), Terraria ($5.00) and Thomas Was Alone ($2.50).

For every purchase, buyers can pick another game from the list to buy at a discounted rate. Buying three games grants players one free Steam key from the discounted games at random. The sale is good until Sunday, November 24.
