playing on laptop

[sum1yum]

just got the game got to the boss in asgard where you have to grab the spear and jump on the hand and press buttons so that you can gradually get up to the vulnerable part?  well....the game wont read my laptop's <- -> ^  buttons on that part of the game.Im pressing it as soon as the icon appears on screen and everytime it shows a directional button, it wont read it and i end up on my butt in the snow. anyone have any ideas? it kinda sucks to have that happen. tried for a few days than i said forget it. ill give it another shot if anyone has any ideas. thank

the <- -> and ^ buttons to different keys, temporarily(e.i. <- would be f, -> would be h, and ^ would be t).
