At the point in the game where i have to get templa disk E. Jumped broken staircase picked up the key and jumped back across the gap and am hanging on the bottom step How do i pull up W key+jump doesn't work What keys should be pressed?

Are you trying to cross that broken staircase right now and had fallen off?

Maybe try just space bar alone or spacebar-forward arrow or spacebar-shift-forward combination.
Try and see. Keep us posted.

sorted mag spacebar only Stuck at ladders at house can't climb up he keeps running back down whats the trick?

Glad you jumped up successfully.

There is a tricky hotspot for that ladder. Move the cursor over the ladder itself and see if that works - also see if there is an up arrow at top of that ladder.
