I could tell it was going to be fun, but couldn't seem to get the timing for walljumping right in browser. Also, are you supposed to be able to tap the keys to move without spending much usage?

The walljump is a little finnicky, yeah - you need to hold the button against the wall, the tap jump.
Also I'm not sure for your other question - the way the game works is the button timer goes down as long as the key is held, and each timer maxes out at 1 second. Theoretically tapping it would work, it'd just drain for as long as you tapped.
Hope it was ok for you, regardless!
