Described by its creator, one man operation ABA Games, as a "Sticky 2d Shooter", Tumiki Fighters is a peculiar blending of classic side scrolling shoot-em-up and Katamari Damacy. Like KD, Tumiki Fighters hails from the land of all things innovative, Japan, and boasts a similarly unique art style, in this case one seemingly inspired by a child's toy blocks.

Taking your roughly aeroplane-shaped collection of pastel coloured blocks for a spin for the first time initially feels like any other Japanese style shooter. Enemies approach from the right. You dodge their fire and shoot them down. Where Tumiki Fighters differs from the norm is that once you've gunned down an opponent you can catch their bullet riddled geometric hulk and attach it to your ship, forming a makeshift shield. Assimilating an enemy with guns grants the player that extra firepower. The downside, of course, is that once the little aeroplane becomes a huge amorphous mass of ordinance spitting cubes and triangles, it also becomes a rather easier target for the enemy. Don't expect that massive turret ripped from the smouldering chassis of the previous boss enemy to last more than a few seconds.

It's a beautifully simple premise and, like Katmari Damacy, one of those ideas that makes one wonder why no one thought of it sooner. Best of all, it's one that you don't have to pay for. The game is freeware, available to download from the ABA games website. Simple, innovative and addictive, this is a game well worth the tiny five megabyte download.
