Unstable Matter

My entry for Ludum Dare 49. Theme: Unstable.

(Note, you'll have to click the game window once after the page has loaded - after that, the on-screen commands will work.)

(Note II: I have not tested this on mobile, and strongly suspect that it will not work on there).

Premise

After one too many nights out partying, the worst thing imaginable has happened! Your physical matter has become unstable as you are! No longer limited to being solid matter, your particles have become so unstable that you can freely become Gas!

But wait! There's more! A notorious party monster called Pill-Monkey Gareth is bringing everyone down. Can you use your new-found powers to bring Gareth down? Find out, in an epic journey that will take you from the deepest ocean to the farthest reaches of space!

(Actually, it's just 3 levels with very similar artwork... But there are weird nose-monsters!)

Gameplay Hints

• Hold A to become Gas.
• Up/Down to move up/down. Left/Right to decelerate/accelerate
• When in doubt, hit things with their own colour (i.e, Gas form makes you red, so hit red enemies in that state)
• Not mentioned in the tutorial, but the pink markers are checkpoints. You'll restart from these automatically if you die.
• The final boss isn't as optimised as I'd like. He will kill you if you touch him in Solid form in either of his states. When you're finishing your attack, make sure you have fully exited his sprite before releasing A and resuming solid form.
