Control a sneaker-wearing kiwi called Tiki, and the aim of the game is to rescue several of your kiwi friends who have been kiwi-napped by Wally, a large blue walrus/leopard seal. Navigate in scrolling maze-like levels, at the end of which they release a kiwi trapped in a cage. The weaponry starts out as arrows, but pickups can change these into bombs, lasers, or bouncing fireballs, each one useful upon the each level. You may also find (or steal) and ride a variety of flying vehicles, including balloons, blimps, and UFOs. Vehicles can be found ready for use or can be stolen from an enemy.
Collecting letters found during your quest to spell out "EXTEND" will take you instantly to the next stage (as in Bubble Bobble). The levels (and sub-levels) get progressively harder and puzzles start creeping in (usually there is no obvious way of getting near the cages and rescue kiwis, so you need to find a way with careful timing and appropriate shooting of certain foes and getting i.e. their balloon to fly, having always in mind the scattered spikes. There are even sub-aqua sections in which Tiki must swim in tunnels (with limited oxygen) in order reach his target.
Another problem is the time limit. Hang around on a stage too long and a big "hurry up!" notice comes on. Then after a few seconds a Devil appears and hits you with his trident, thus removing one of your lives (similarly situation as in Bubble Bobble)!"
The NES conversion is fine in terms of graphics, although its colors are not that accurate due to its palette limitations. Other than that, the graphics here are ultra-cute and varied, as they cover the different environments of mountains, caves and seas, but without offering any special graphics effects really, much like the original. Note that the colors being used in the Master System conversion are way more accurate to the original when compared to the NES version. Sprites move smoothly and quite fast on the screen too.
What is really impressive here is the music! It is one of the best arcade music conversion I found for the NES console, really! Along with the great tune, there are several SFX accompanying gameplay, all taken also from the original.
