Once you have a feel for the game, come back to the first level.
It's basically a tutorial level, no cheap traps. Since you've already played it for coins etc you can essentially speed through. I'd recommend using Monkey, and keeping your dodge button handy. You should try to move fast, so you can hop over falling platforms and such as they come at you. It's not too tricky, so no need to memorise the level. Watch your health bar, and if you take some hits, switch out to another character (like Sandmonk) to make sure you don't die from cumulative damage.
The only tricky part (which got me the first time) is right near the end, there's an ice slide, and you need to be playing a gliding character so you can launch yourself over the spikes at the end.
If you do die, just play to the end, and try again. It should take less than 10 minutes per attempt, and there's no reason you shouldn't be able to cruise through it within 2-3 tries.
