Your main goal in Oroboros is to protect your fragile tail while collecting the snowflake-like energy clusters that float on and off the screen. Your tail grows as you chow down on energy, leading you closer to your goal of opening a portal. But with a longer tail comes a greater danger of it being hit. Click and hold the left mouse button to coil it around your head for protection. Keep an eye on the stamina meter to the left, as when it runs out you won't be able to stay hidden any longer!
Each new dimension starts with an upgrade screen that allows you to spend evo points to enhance your abilities. Strengthen your tail or increase your agility to make the coming dimensions a bit easier to handle. The menu also introduces the main enemy of the level and gives you hints on how to evade it successfully.
Analysis: Oroboros doesn't come across as much of a game at first glance, but after playing through a few levels you'll realize there's surprising depth to it. The evo system adds a nice level of pseudo-strategy to the arcade-style title, and it gives a limited sense of progression as well. One of the game's biggest strengths is its audio and visual presentation. Think retro Atari vector meets new age sci-fi, complete with a techno soundtrack.
Oroboros is an excellent arcade "shooter" (avoider?) with loads of style.
You can also Play Oroboros at Kongregate.
