This achievement cannot be missed, just simply complete chapters 1-4 to receive this achievement. Levels 1-4 are quite simple so you shouldnt have any trouble getting past these levels.
Notes:

Avoid Stage 3's Secret Room until your chosen character is at least level 20. Expect to deal with Faust's magic, the exploding purple hornets, three red and six crystalline enemies. The enemies that essentially turn into big bullets of energy may also pose a threat if your HP stat is low.
Stage 4's boss will kill you instantly unless you jump on top of one of the walls. Sure it seems logical that standing behind the wall furthest from the cannon would shield you, but you can easily see that it melts through all of the walls, and you, without much issue.
Boss 1: this boss appears on the first level, he is very simple to beat you shouldnt have any trouble. Just simply keep hitting him and he will eventually die. Whenever he jumps to the other side of the map wait until he lands then continue to attack him.

Boss 2: this boss appears on stage 4; now this boss can be tricky at first if you dont know what you doing. Basically you have you wait until the boss opens up his defence then start to attack him. Now once you see red lights on the ground run back and wait for the blocks to drop down. Once they have you need to quickly jump on top of them will he fires his laser Then all you need to do is simply repeat the process, but be warned there may not be 3 blocks to jump on so keep on your guard.
