Combining the graphical style of the ZX81 (that would be an ancient black & white 8-bit British micro) with the visuals of those LCD handhelds of yore, 4NR by P1XL is a delightfully retro iOS offering. Unique style aside, 4NR is also a truly great puzzle platformer with a simple yet effective plot, an assortment of interesting and uniquely mixed mechanics and absolutely excellent controls that starts off with a major dilemma. Do you seek higher ground as instructed by an incorporeal voice or do you enter your way more familiar underground caverns?

4NR is available as a universal iOS app and will only set you back $0.99. The game even supports those arcade controllers many seem to actually own.
