The controls are very easy to master – left, right, up will allow high jumps(but can’t be combined with horizontal ones), down will let you duck and roll through small gates, and down in mid-air will trigger a hard-fall that can break the breakable stone blocks. On your way to the top you’ll have to be careful to special blocks – yellow ones are extended/contracted by special “key” blocks(marked with an exclamation sign), green ones are moving periodically, red blocks retract when touched. You’re likely to meet various enemies as well – spiders or spiked turtles – they won’t kill you but will leave you unconscious for a while – which makes you lose time, which increases the chances you eventually drown.
