Monkeys vs. Zombies with a 2x button: click it during a level and the whole lawn runs at double speed. Click again for normal.
Monkeys vs. Zombies, with a fast-forward button.
This is a remix of Monkeys vs. Zombies by HippieGod: Bloons TD 6's monkeys defending the Plants vs. Zombies lawn. It changes one thing: it adds a 2x button.
Everything else. The game's files are HippieGod's 0.21.0, unchanged, and it uses the same saves as the original, so your progress carries over.
Your own Plants vs. Zombies: Game of the Year and Bloons TD 6, the same as the original. The first start takes a minute or two on the title screen while the monkeys' art is built from your Bloons TD 6.
The button is one small add-on file, version.dll, placed beside the game. It sets the speed multiplier the game's engine already has, draws the button and takes the click on it. It only switches on for the exact 0.21.0 build, makes no network connections and changes none of the game's files. Delete version.dll and the game is the original again.
The mashup itself is HippieGod's work; its credits are in CREDITS.txt. This remix was made with an AI coding agent.
