This game is very, very easy to 100%. It should take under 2 hours, and if you don't want to even read this guide, simply eat everything and you'll get every achievement. However that will take longer than if you follow this guide.

The achievements have some grammatical errors that I will not be changing.

The goal in this game is to absorb elements until you're big enough to absorb everything. Certain creatures don't show up until you go to higher levels via the vortexes.

Eat a few elements right as you start the game. (The stationary orbs)

Attack any enemy that's larger than you. You can do this immediately at the beginning by trying to eat the Sparkle before you eat any elements.

Just keep eating elements until you change from attached orbs to something else.

Now that you've eaten enough elements, you should be able to eat that other Sparkle where you started. If the achievement doesn't unlock from eating him, keep eating elements until you can eat the next one. Here's a picture of the Sparkle that got it for me.

Use your mouse wheel to scroll down (to go up) or up (to go down) between vortexes. The vortexes don't move as you go up and down them.

Eat one of the elements stolen by the arrow-looking creatures shown below.

Just go near the Discus creatures (gear-looking things shown below) a few vortexes above the start and they'll bump you.

Kill a Medusa creature (one of those jellyfish-looking creatures shown below.)

A protected element is shown below. To absorb it you have to wait until the arrows pulse (about 3 times) then shoot out. Afterwards, carefully move between them and absorb the element inside. The arrows will shoot you out in the direction they are pointing if you touch them.

Whenever you reach a higher level through the vortexes, eat other Sparkles. Eventually, if you aren't big enough to eat the Sparkle on your level, absorb more elements until you are. Keep this up until the achievement unlocks. Stated earlier, you should be able to unlock every achievement and this one in under 2 hours.
