heres an idea just popped into my head slow motion as well as a pause play option to be able to rig up things that combie like a mine next to a person with a box above while paused you can manipulate the environment and then unleash what you have created by clicking play
message for the developer when climbing on the professional ranks you should make the coins speed up the climbing speed so they go higher up from the lava because if you jump from edge to edge you loose speed and then get eaten by lava
