Flynn Arcade's "Galacticon" is the echoing answer to the ZX Spectrum's Jetpac. More or less. It is a spiritual successor to that early 80's platform shooter, and while there's obvious similarities everything that Jetpac achieved in the retro gaming realm back in the day was improved upon tenfold in Galacticon. With Galacticon you'll find a very retro looking experience that pays homage to the source material, but in an incredibly updated way. In a way that is centered around collecting species trapped by humans, and dropping them off in multiple teleportation pads. A contrasting effort to Jetpac's fueling up, and constructing of a rocket to get to the next level.
In a similar fashion Galacticon also grants the player only three lives initially with which to make it as far as possible while completing objectives, shooting enemy craft, and using a species combo system to score bonus points. This is all done via an alien God/Machine hero who gets around on a jetpack that gains power from power-ups.
