I beat you to the "MASSIVE LIST OF STUFFZ" a long time ago.

Anyway, you managed to convince me to REPOST THEM ALL. MUHUHAHAHAHA.
I have a charge cannon in there somewhere that I think would be awesome.
REPOST:Things I would like in the level editor:
The interconnected levels (already acknowledged and accepted)
Exclusive equips/weapons that aren't in the actual game. Would be useful with the above, since we could reward secret hunting.
Alternate means of gaining health. Similar reason to the above.
More ideas!
Remote controlled bombs.
Skill books. New talents for out intrepid hero!
IE: Throwing ropes sideways, to make a bridge.
Improved whip talents (Indiana Jones style grappling, perhaps?).
faster gun reloads.
And of course a new appropriate themed store.
Annnd more.
Being able to erase the boundaries, to create bottomless pits and perhaps even exits? I'd like to make dropping in a pit lead to a new room.
Cushions: Blocks you can land on that give no fall damage. You still bounce when you hit them if you fall from high enough.
I like the idea of shoes that increase speed, maybe you could run fast enough to glide over water?
Actually glide gives me an idea.
Hang glider: If you do a running jump, vastly improves jump height and reduces fall speed by more than the cape or parachute. Exclusive of cape and Jetpack.
Wind currents: Pushes you in mid-air Can be any direction. More effective when slowed down, allows you to vastly improve speed if using the hang glider. No effect if you're planted firmly on the ground. Alternatively, lessened effect when on ground, no effect if on ground with spike shoes.
Weapons that can be aimed better than just "left or right". So far only throws have this freedom.
Something that can launch you in a direction in mid-air, ala FLaiL.
A teleporter that stops when it hits a wall, less likely to kill you, but less useful in some regards. I say "less likely" as opposed to impossible because of lava and the like.
for custom level exclusive weapons, Excalibur keeps coming to mind. And ray guns.
Double jump. less useful than the Jetpack, but let's you save the jetpack for later if you're making a metroidvania style set.
Rocket launcher. enough said.
Enemies that don't respawn if you leave and come back. You could make bosses that way. Possibly walls, but that might be difficult to do.
Damn I have a ton of these.
And I have an improvement to the hang glider: A jet Glider.
It works like the regular one crossed with a Jetpack. Activating the jetpack while gliding boosts your horizontal speed, and allows you to kill enemies by hitting them.
Machine gun: Simple enough.
Charge cannon: SUPER WEAPON. Charges up for a short time before firing a blast. very similar to the beams aliens use, but horizontal. Also sucks in nearby objects and shoots them with the blast, which would be really awesome with enough stones lying around.
Alternatively, a weapon with just a second part. Sucks in a launches anything nearby that can be thrown.
something to let you push/throw knocked out enemies around?
Platforms that only work/appear with a certain item. The logical opposite of a locked door.
Sideways springs, to launch the player away from walls.
