Between Nyan Cat being the main star, the bacon strip cursor, and the background appearances of Neil DeGrasse Tyson, Pedobear and Hitler (🎶two of these things are not like the others🎶), you can instantly date this to the first half of the 2010s. ESPECIALLY the frivolous use of Hitler - that comes off in pretty bad taste these days.
The basic gameplay's pretty fun, though - can't exactly go wrong with having the player bob and weave through obstacles.
Would've liked to have had an autofire for the lasers - holding down this mousepad is hell on my finger.
