Raider: Episode 1 is an "old-school" style platformer which aims to be fun yet challenging. The first episode of a series of five, the story follows a character who looks a little like some badass version of Sonic (there's even checkpoints which resemble the Star Posts from Sonic!) on his quest to explore a mysterious ship.

There's some great platforming to be found here and it does indeed feel sufficiently retro. Towards the end it starts to become a little too dependent on precision timing of jumps, but some would argue that that's how games used to be.

Have a crack and see what you think. (Thanks to IndieGames reader jack_in_the_dark for the suggestion!)
