When you're an old, washed up action hero, getting back to the top fuels you – almost literally. Action Henk by Dutch developer RageSquid is a speed runner/platformer set in obstacle-filled levels challenging you to butt slide as far as you can.

You star as Henk, an old action figure who must race other toys for the best time through complex Toy Story-esque constructed levels. Your butt slide is your calling card, and it propels you forward. Going the distance and completing levels is all about timing your jumps and preserving your momentum to maximum effect. You can also use gadgets like a grappling hook to make your way. It's fast and addictive – imploring you to post your best time, compete against friends' ghost times, and keep coming back for more. It's a game of adrenaline, close calls, and the fun kind of frustration.

The game is currently in Steam Early Access for $9.99 (PC, Mac, and Linux), and its first update has added levels (now up to 25) and the extreme difficulty of Rainbow medals and also fixed some bugs and made other improvements. It can also be bought at the Humble Store.

Future updates aim to include over 50 levels (including outdoor levels), extra gadgets like a pogo stick or RC truck, six playable characters, and a level editor.

Developer RageSquid says that it hopes to have the game finished in late 2014/early 2015, but might take more time to incorporate ongoing requests from the community.
