Naming Conventions

You're not expected to adhere to these terms 100% of the time. They're meant more as just the default option. It's always okay to spell things out fully as well.
Officially the tiles are called just that, tiles, but I think when talking about solid tiles, you can also say "block".
Jetman The name is mentioned once in the hintbook.

Ladder
Moving LadderUp/Down LadderThese look the same with the animation running in opposite directions. This makes them difficult to tell apart in screenshots. In the big .png's on the levels subpages, the end with the grey bar indicates the direction the ladder is scrolling. In the smaller, in-editor shots it's the end that has a white bar.
Door/Exit Has to open fully for exiting the level. This takes a little while, which may affect routing.

Randomness

Uses Borland C / Turbo C++'s rand() function. Which is a LCG PRNG, which works as follows:
uint32_t seed; //Seed is 32 bits
int rand()
{
  seed = seed*22695477 + 1; //Seed multiplies and adds, and possibly overflows
  return (seed >> 16) & 32767; //Use bits 16-30 for requested random value
}
Using phaser (even if not trying to phase anything) seems to use RNG throws.

Enemies

NameSpeedBehavior
TrackbotHorizontal: 43 sp/f, Vertical (ladder): 33 sp/f Affected by gravity. Generally heads in your direction. Makes random decisions at ladder/floor intersections - these can be manipulated through phaser usage, although some decisions cannot be changed.
Steel Ball / MarbleHorizontal: 59 sp/f Affected by gravity. Reverses horizontal direction when it hits a wall.
SpringVertical: 50 sp/f Reverses vertical direction when it hits a surface. Takes 5 frames to reverse direction.
MissileHorizontal and vertical: 64 sp/f Does a 90 degree clockwise turn when it hits a wall.
Spikes / SpinnerHorizontal and vertical: 20 sp/f Moves diagonally at all times. Bounces at a 90 degree angle when it hits a surface, and will reverse direction completely if it hits a corner perfectly.
FlitzerHorizontal and vertical: 11 sp/f Randomly moves in one of eight directions. Changes direction when it hits a wall, otherwise changes direction every 7 frames.
BatbotHorizontal: 10 sp/f, Vertical: 17 sp/f Will head in your direction once it hits a surface, the movement is not random. Capable of moving diagonally.
HomerHorizontal and vertical: 4 sp/f Moves diagonally until it matches your x or y coordinate, then travels in a straight line at you. Can move through all blocks.

Known tricks

Movement

Extreme Jumps

The following jumps are extreme cases of what is possible to perform. Some of them are easier if you get a running start, i.e. there is more than one block for acceleration (even though there is no acceleration for running). The format (X,Y) has distance covered horizontally and vertically in blocks (positive values are rising onto higher ground).
Onto a ladder means being able to grab a ladder in the square indicated. Onto a platform means being able to land on a platform in the square indicated.

ToDo

This section is useful to have so multiple people don't end up doing the same work. Just add it here and it will get done, as if by magic! :) Use ** if you want to express you're going to do one of these to avoid overlapping work.
