BarrierGame app for iPhone and iPad

31 levels! 14 different color schemes! BarrierGame is a unique minimalist intelligent-arcade game where you control two sliding doors of a large barrier so as to let the "good" squares through and keep the "bad" ones out. For the best experience, hold your iPhone or iPad with two hands and use your thumbs to control the doors.

NB! This game is intentionally hard. In a carefully considered intelligent way. Thats what makes it special for those who enjoy a challenge. Figuring out exactly how to play and what the various numbers are telling you is part of the game and part of the fun! The joy you will get from figuring it out is well worth the effort! Exploration and making discoveries are among the most satisfying human activities! (well, Im a scientist :)

31 LEVELS
some of them fast and action-packed, some slightly calmer and more meditative. You can play them all through in the given order, from 1 to 31, or also directly select some specific level to start with.

Additionally, each level can be played in an "Endless" mode where you can either go for new records of how many "goods" you can let through at that level while keeping the "bads" out, or, alternatively, you can just focus on the process of playing without any numerical goals and enjoy the flow.

14 DIFFERENT COLOR SCHEMES
for you to choose from as you prefer or need (in the "Briefing" section of the menu in the game), and changing the colors every once in a while is an enjoyable experience all by itself!
