See JEDIGEG's last comments for details of how to start the game. As he mentions. The moving arrows that i thought were a loading screen, were in fact indicating that you should click on the image with the LMB and drag it in the direction of the arrows. Unfortunately I don't have time to check this game out and post a short review now (it's 7pm here in the UK) as I'm meeting up with online friends for some gaming. I have provided a link below to Steam community reviews.

This is a mouse controlled platformer, where you use your mouse to swing from platform to platform avoiding the various traps, using a grappling hook controlled by the mouse. It's not very easy to control and I reckon you'll be pulling your hair out after several attempts. It's not Super Meat boy, but a very brief try left me with virtually no progress as I found it difficult to control the movement. The principle sounds great and reminds me of one of my older favorite platformers called Wik and the Fable of Souls, where the protagonist uses its tongue to swing from platform to platform; however graphically Hard man doesn't come close to Wik for visuals. You can see the Steam community reviews of Hard Man which are mainly negative HERE, (due in part to the control mechanism, which some Steam community members are saying it's really hard to control precisely). The last two images are from the Steam store page for the game which costs £0.79/$0.99.
