The Adventure Factory

I discovered this nifty platforming game level editor that allows you to make little adventures to torture amuse your friends with. I got so into it I ended up making 5 levels which I'll link past the break so that you can all berate my terrible level design skills. Note that I had to beat these things to upload them; So yes, they're all possible.

You control your character with the arrow keys (up to jump) and use space to attack. Each of the characters has a few special skills you'll discover along the way.

(Level codes continued below)

In order of difficulty:

Dark Castle Siege:  e8491e9a6fb2ceedc379536d9668b3ee
    (Hint: Press down to crouch and spin through small passages.)

Brutal Mine Clash:  67c4f0b90f6cb80f90ad829fd8277488
    (Hint: If you press space in mid-air you’ll do a downward smash.)

Insane Jungle Adventure:  b8bf830d439be3707dcf466ffe608a0c
    (Hint: That the sticky stuff you start on prevents you from jumping; Find a way off of it.)

Dangerous Crypt Raid: 16e2fd3bd9664d5885ab31d3b219b033
    (Hint: The level is setup so that if you make it through at full speed all the crystals will be open for you.)

Daring Relic Crusade:  2ed980bf09c676ee1e39111475afbdaa
    (Hint: Dr. Montana can climb almost anything and his shots intercept fireballs.)

Let me know if any of you can actually finish all of them, and post any levels you create in the comments below!
