The block-pushing puzzler first got started with “Sokoban” and has continued through to today. This is evidenced by titles such as Abyssal Zone which just hit Steam Greenlight today.
In Abyssal Zone, players get to control a slippery squid as it goes through various 2D stages. Typically the goal is to solve a puzzle by moving pieces onto triggers which open pathways. However, enemies are in pursuit and may catch players who make mistakes.
There will also be a few exclusive co-op puzzles for two players to enjoy. Check out the Greenlight page to learn a bit more about Abyssal Zone.
