Last week, Indie Royale were offering up five indie titles in their new ‘Alaska Bundle‘ for PC users. Pay-what-You-Want for the following games and the sixth game will be revealed at a later date. Today, we can reveal that sixth title is ‘Flipper‘ and has now been added to the Alaska Bundle. Flipper is playable on Windows, Mac and Linux and is a minimalist puzzle game. Tap the blocks to cycle their colours to match the pattern shown at the beginning of the level. Designed to test your mind and memory, it quickly leads to mind-boggling puzzles.
