retroFuture's zX is not like most shmups. Instead of encouraging passive play or requiring the player to dodge a ton of bullets, players should dive straight into the line of fire to reflect enemy shots and power up their hyper gun. My closest analogy would be the kamikaze-like Psyvariar or Mars Matrix, except players don't buzz or absorb bullets here. Also unlike most shmups, zX's levels are more bite-sized.

In-game tutorials explain most of the controls. To enter portals or use the reflecting blade, press the space bar, despite the in-game tutorial telling you to use the up arrow. While the Windows demo offers 11 levels, the full game has over 66. These are divided into 6 zones, each comprising of 10 levels and 1 boss level.

Those fond of the demo can vote for zX on Steam Greenlight.
