Your main objective is to reach the biggest bubble to finish the level and get an achievement, and reach it within the time limit to get another. Hold LMB to get attracted to the green bubbles and progress through the game (attraction is only possible when the crosshair is red). RMB enables psychedelic mode, but this won't help you in any way so avoid pressing it (it can be disabled by pressing RMB again).

Very easy. Just follow the linear path to find the goal at the end.

A bit harder than the first. Try to go past the first "mountain" by taking both starting bubbles (for a shortcut), then follow the path, climb up, and head right to find the goal.

Easier than second level. Go down from the starting point, then follow the straight path all the way to its end.

Go all the way forward from the starting point. The goal is at the very end of the linear path.

The goal is at the right hand side from your starting point. Take and go past the first bubble without colliding with it, then take it again but aiming to the spawn point. You should see another bubble at the distance (right side). Approach it, and now head all the way to the left.

Take the left intersection thrice to get out of the maze. Then, once outside, go all the way to the right.

Goal is under the starting point. Take the first and second bubbles up (without colliding with the first), then take the first again while aiming down to descend. This takes some practice, but once you get to touch any of the bottom bubbles, you're set.

Take the first three bubbles (straight and upwards), then go all the way southeast and enter the pipe. Goal is at the very end.

If you're still missing consecutive collisions achievements after completing the game, replay level 6 and collide with every bubble you see inside the maze, then finish off with the ones outside.
