If you want more Cut the Rope: Time Travel [Free] and Time Travel HD [Free (HD)], now's a good time to mash the update button. ZeptoLab has added a new "Disco Era" set of levels to the puzzler. In these, you'll cut the rope and position disco balls to stop "beams" from zapping all the candy. Sounds like a neat twist on the series' proven formula, which overall, is a thing Time Travel has been doing pretty well.
If you'd like to grab this, just hit "update" since it's free and all. Also, buckle up for a lot more content, as ZeptoLab has proven it supports its titles over time.
