So far as I know, any Mac with about 350k free RAM.
The greater the bit depth of your monitor, the more memory needed and the game might slow down, depending on your computer. (By default, the RAM is set to what I needed to run it in thousands of colors on my computer. The speed limit is also set to just slower than my computer - 120MHz - handled at thousands.)
Physics:
The ball behaves like light: angle of incidence equals the angle of refraction. In other pictures, if it comes in like this:
it will go out like this:
(Okay, so the angle is supposed to be relative to the normal, but same difference… ;-)
Then there's a bu--I mean, "feature" that allows the ball to slip through the crack between two balls. In a densely packed cluster of blocks, this can really help -- until you reach the death block on the other side…
Menus:
In normal game-playing mode:
File
New Game - Ends any game (including practice mode) that's currently being played and starts a new one.
Pause / Resume - Pauses or resumes the current game.
Quit - Quits.
Options
Sound On / Sound Off - Turns the game's sound on or off. (PPC only)
Draw Fastest / Draw Normal - The lower the bit depth is of the monitor, the faster Quickdraw (i.e. the System) can do what I ask it. By default, the speed is limited to doing the program's loop no more than once every 1/30 of a second. This option takes away (or reinstates) that limitation, making it possible for the ball to travel at much greater speeds.
Practice - Gives you 5000 lives, -50000 points, and repeatedly loops the same level. Select New Game from the File menu to end.
Edit Levels… - Let's you mess around with all the levels.
Reset Levels… - Reverts all level modifications back to my originals.
In practice mode:
Same as above, just one extra menu:
Levels
Let's you select level to practice on.
In editing mode:
File
New - Creates a new, blank level, which is inserted after the one currently selected when saved.
Save - Saves any changes to the level.
Quit - Quits.
Edit
Set Name - Sets the name of the level.
Cut,Copy,Paste - Do the usual, just with level information…
Delete Level… - Deletes the current level.
Levels
Selects level to edit.
Editing Levels:
Entering editing mode changes the screen to a grid. At the bottom are the 6 different types of blocks, plus a weird one with an "x" in it. To change a level, simply select a block and plot it on the grid. The "x" block deletes mistakes. The numbers 0-6 can also select a block type, and the left and right keys move you among the levels. Use the menus to create, cut, copy, paste, delete, change levels and all that fine stuff. Pretty straight forward....
Version History:
1.1 - The following changes:
•Level editing added.
•Practice mode added.
•16 color requirement eliminated.
•Level names added.
•Bug fixed where ball would remain at speed of previous game.
•Automatic pause added when not front most application.
•Error detection improved.
•Default prefered size increased to avoid problems.
•Version number in Finder's "Get Info" added.
1.0 - Initial release.
Troubleshooting:
Three things:
1) Use the "Get Info" command in the Finder to increase the prefered memory size.
2) Decrease the number of colors at which your monitor is set.
3) Disable the sound.
Known Bug:
- When I ran the 68k version under emulation on my PPC, every once in a while it didn't play a sound when it should. However, when I ran it on my LC III, sometimes playing a sound caused it to crash, so I've disabled sounds on 68k machines or when emulating on a PPC.
