Scratch Game Tweaks & Integration

My Scratch project is already live, yet it needs a few finishing touches. First, the victory screen must swap to a new background image I’ve generated with AI; the file is ready in PNG format. Alongside that change, a fresh sprite should appear during the win sequence, complete with its own simple animation.

The bigger task is to merge this game with another Scratch project that currently sits in a different account. Once combined, both games should run under one profile without breaking any existing variables, scripts, or assets. I’ll share the two .sb3 files plus temporary access to the second account so everything can be migrated safely.

Acceptance criteria:
• New winning background displays at full resolution and doesn’t obscure UI elements.
• Added sprite triggers correctly, animates smoothly, and introduces no lag or cloning glitches.
• Integrated project fits within Scratch’s 10 MB limit, loads quickly, and shows no freezes on Chrome desktop or the Scratch mobile app.
• All original gameplay features of both titles remain intact after the merge.

Development should be done in the Scratch 3.0 editor (online or offline). Please work on a duplicate copy first so I can test before we publish anything live.
Note: I need it to be done in 3 hours from now
