Just like the original game, Errro 2 features a screen-wrapping mechanic. When you walk off of the left edge of the screen, you appear at the right edge of the screen; when you fall off the bottom of the screen, you appear at the top of the screen.
In the sequel, though, you will also discover various new gameplay mechanics such as world rotation and Gravity Bombs. In the end, you will have to combine all of your skills to complete the 100 puzzle levels available.
Errro 2: Outer Space also debuts a completely new gameplay mode called "Darkslide." In Darkslide mode, you can play through 30 multi-screen levels that constantly scroll from the start of the level to the end of the level. Not only do you have to think creatively to solve the puzzles in the level, but you also have to do so quickly to keep up with the scroll!
You will also find a new DLC system that lets you quickly browse for new levels and download them in seconds. Once you have completed the original levels, you can continue to enjoy new DLC levels to challenge your skills.
Continuing, Errro 2 also includes a brand new Challenges system. The challenges function much the same way as "achievements." Every level presents you with a series of challenges to complete. Some you will complete with ease, but others will require you to approach the level in entirely new ways!
Theatre Mode allows you to save and watch replays of levels you have completed. After you have perilously sidestepped the spikes and the pitfalls to finish the level barely on time, you can sit back and watch it all over again to see all of the cool moves you made!
Also of note, the game capitalizes on the replay engine to provide an in-depth set of popup-video style video tutorials. Instead of merely reading instructions on what object does what, you can witness firsthand how they function before trying them out for yourself. Plus, each of the puzzle levels gives you the option of viewing a brief but useful video hint in case you become hopelessly stuck on a puzzle level.
Wrapping up, Errro 2 comes with an array of sound effects, and with over 20 minutes of music you won't have to hear the same loop over and over. You can toggle these settings among others (such as complete keyboard / gamepad / joystick customization) in the preferences menu.
Thanks for taking the time to read about my game. I hope you find it challenging and enjoyable!
