Action Henk is a fun casual game that should appeal to gamers of all ages. The premise is simple. The game is a series of "race" tracks where you're racing against the clock or against other people in the multiplayer modes. If you've ever played a game from the Joe Danger series or to a lesser extent in terms of comparison, the Trials series, you'll have an idea of what Action Henk is all about. Another game I found it easy to compare is the Bit Trip Runner series. Basically every course is based on simple physics, speed and momentum. Your goal is to finish the track in the fastest time. There is a good deal of variety throughout the courses, with your buttslide and grappling hook coming into play at various times. You'll have to learn to time your jumps and nuances of particular courses to get the fastest time.
+ Very fun graphically. This game doesnt take itself seriously.
+ Variety of tracks.
+ Friends leaderboard.
+ Steam Workshop support. Create your own tracks!
+ Wide range of courses that unlock after a certain amount of medals in the section prior.
+ "Ghosts" and replays to see where you messed up or how to tackle a tough obstacle.
- The music is abysmal.
All in all, Action Henk is a good entry into this genre of game. It encourages competition, but at the same time keeps it light and fun. The track creator is fairly robust and hopefully Workshop support will encourage people to make new and even better tracks.
I recommend Action Henk if you are looking for a fun game with a competitive spirit.
