changed how the game determines how long before a piece falls (includes a larger difference between the slowest and fastest speeds), and made it so piece movement is faster in faster speeds
changed how the computer determines where to place a piece, and made it not always drop immediately (should make the game easier)
made it so you can move a piece farther while it's falling
added a warning sound and exclamation mark when a side is almost full
made the sound of a piece dropping more audible and made its pitch indicate where it was dropped
show the current mode above the score
fix the description for the 2-player modes again (should be ASD, not WAS or WSD; it's up that this game doesn't use)
fixed a bug where touch controls wouldn't show up when Auto was chosen (the default)
removed the analog touch control options from the menu (that was part of my template, but it doesn't apply to this game)
# 2023-08-19 (1.1.1): fixed a bug where the background of the pause screen is black on some browsers
fixed a bug where the game could give an error message when clicking a shape (I mainly noticed this in the computer-plays-itself mode, but it looks like it could happen in the normal game, too)
two-player modes should now work on touch screens
changed how scrolling and zooming work on mobile; I hope it's better
menu items now activate when you release the mouse button or touch, instead of when you first press the mouse
put a "Reload" link in the page footer when added to the home screen, since there wasn't any other way to get it to update on recent versions of iOS (switch to "Inline" mode in options, then scroll down)
miscellaneous changes/fixes to the code common to all of my games (including changes to error handling, and a few internal changes that shouldn't affect how the game functions)
