So I downloaded this game on my phone to see what we could expect once it drops on console.
Getting to level 10 is super easy. It took me about 3 & 1/2 minutes to do it on my phone with the garbage touch controls, so I bet you could do it even faster with a controller.
I know the achievement only asks for you to reach
level 10, but trust me it's worth getting to level 11. Once you hit 11 you can just hold left and die over and over until you hit 500 deaths.
At 1 death per second (totally feasible), it'll take you roughly 8 minutes to get to your 500 death count.
So you can expect a 100% completion in 10-15 minutes
depending on how good you are at platforming games.
