Quick Answer
For a bad ending, finish Jay's red fourth stage or fail every day from the start in Lacey's Diner. These are separate routes, not one global ending. The relevant official achievement names are Goodbye j̵̀̊̾͊á̶̯͊̓ý̴̛͂̕ and Diner.
How do you trigger Goodbye Jay?
Complete three regular stages, enter the red fourth stage, and let the final death presentation finish.
“Goodbye Jay” below refers to the achievement displayed as Goodbye j̵̀̊̾͊á̶̯͊̓ý̴̛͂̕. You follow this route inside Jay's Skating Game. If you need help reaching that point, use the Jay's Skating Game walkthrough.
Complete the first three stages
Finish the first three regular stages of Jay's Skating Game. These stages come before the red stage needed for this route.
Continue into the red fourth stage
Enter the fourth stage, which has a red background. Keep the minigame open and let Jay reach her final death.
Watch the presentation through to the end
Let the entire death presentation finish without closing the game or interrupting it. The achievement check happens after the scene ends. Reaching the red stage alone does not complete that sequence.
Wait through the whole presentation if you want the achievement check. Closing the minigame before it finishes interrupts the required sequence.
How do you start the Diner failure route?
Let the timer expire on the first day, then keep failing every following day until the special kitchen appears.
You take this branch inside Lacey's Diner. The corresponding official achievement is Diner. Use the Lacey's Diner walkthrough if you need the wider minigame context.
Fail the first day
Start Lacey's Diner and let the first day's timer run out. Begin with failure rather than trying to serve customers successfully.
Keep failing on following days
Continue letting the timers expire on every following day. Watch the failure scenes as you continue along this branch. Keep your results consistent instead of alternating successful and failed days.
Watch for the special kitchen
Continue the same failure pattern until the special kitchen with unusual ingredients appears. That kitchen is the checkpoint described here for entering the Diner failure branch. Further steps beyond this checkpoint will be added as details become available.
Alternating successful and failed days can cause the minigame to close. For this route, stay with consecutive failures from the first day.
Is Bad Ending an official ending name?
No: Bad Ending is a descriptive label, not an official achievement name or one global ending.
Good Ending, Secret Ending, and Stalker Ending are also descriptive labels rather than official ending names. Use the named achievement and minigame to identify the branch you want. The Lacey's Flash Games endings overview helps you distinguish those routes.
The Diner failure sequence is called a “bad ending,” but that wording does not establish a single game-wide finale. Goodbye Jay belongs to Jay's Skating Game; the Diner failure route belongs to Lacey's Diner. Choose the route by its minigame before following the steps.
