Sega has just started publishing other developers' games on the App Store through an initiative called Sega Alliance with Jack Lumber, a game by the folks who made Smuggle Truck (or Snuggle Truck, if you caught it post-censorship). This is a title that's heavily inspired by the great Fruit Ninja, but instead of just ripping off Halfbrick's apple-slicing classic, it actually iterates forward on that game quite a bit.
For one thing, instead of just slicing through the air as quickly as you can, Jack Lumber will actually pause and slow down the logs you're meant to be cutting through, which lets you set up a little more strategy to your slices. You can cut through multiple logs in one swipe for bonus points, and some logs have to be cut in a certain directly, or chopped twice for maximum points.
The game's great fun, and the goofy "Trees killed my grandma" cartoon aesthetic goes a long way towards making the game really colorful and interesting. If you like Fruit Ninja, Jack Lumber is a must buy, and even if you're looking for something new from a line-drawing game, this one's well worth a look. Sega definitely started off its publishing choices right. Jack Lumber is universal and available from the App Store now for just 99 cents.
Edit: A previous version of the post listed the wrong publisher. Apologies for any confusion.
