One of our favorite games of April went free today, Babylonian Twins [Free], while its HD iPad counterpart, Babylonian Twins HD [$1.99] saw a price drop to $1.99. Regardless of which version you get, both are a lot of fun and the game has an amazingly interesting history involving extraordinary conditions during its development in Iraq with economic sanctions preventing its initial release.

As the title would hint, in Babylonian Twins you play as a set of Babylonian twins, with each twin having their own abilities which must be cleverly combined to complete levels. Gameplay is very similar to that of the classic Blizzard game The Lost Vikings, with only one twin able to be controlled at once. We loved how this gameplay mechanic was combined with challenging, well designed levels in our review:

These simple gameplay features form the premise for some of the most interesting and expansive level designs that we have seen to date on the platform. In many ways, Babylonian Twins does away with contemporary trends in gaming, and re-instates the old-school values of a challenging, explorative platformer that refuses to hold you by the hand. There are no directional arrows or maps to point you towards the golden palm trees you must collect each level. In fact, even crucial objects such as the aforementioned broken walls and floors are easily missed unless you’re paying attention. And each level is enormous– an adventure in and of itself– many of our completion times clocking in at around 30 minutes each.

The iPad version of the game plays the same, with higher quality graphics as is the case with most “HD" releases. Give the iPhone version a try, and if you like it and own an iPad, Babylonian Twins HD is well worth the two bucks. Regardless of whether or not you pick up the iPad version while it’s on sale, Babylonian Twins for the iPhone is a game everyone should download to try out while it’s free.
