Despite its cruel difficulty, Spacejacked is a really fun and entertaining game that will probably have me crawling back to it in shame again and again. Its hilarious dialogue had me in stitches on more than one occasion, and the gravity suit mechanic really adds a creative element that I’ve never seen before in the tower defence games that I’ve played.
Spacejacked is a more than competent platformer/tower defense title that falls short of being truly memorable, but perhaps it's most interesting for its iteration upon and juxtaposition of prominent game ideas, like VVVVVV's gravity-shifting, the retro-cool revival of single-screen arcade games like Woah Dave, and, hell, the main character bears more than a passing resemblance to Gordon Freeman (or am I just going crazy?)
If nothing else, Spacejacked easily meets the most important criteria I have when reviewing games — fun. Its frantic pace, interesting take on the genre, and well-executed mechanics make for an enjoyable experience. The design and sound may not stand out, but they’re certainly not bad.
