About

OpenTower is an almost fully accurate Pizza Tower decompilation, without optimizations and with no unused content removed. It is aimed at more experienced people who prefer to mod without the code holding their hand. The repository contains no datafiles, sprites or sounds, so the game's own files are needed to set it up.

Getting started

You need Pizza Tower from Steam, a specific GameMaker version, the Steamworks SDK and UndertaleModTool. Run the included decompiler script from UndertaleModTool on the game's data file, pick the project folder so it dumps the sprites, then open the project in GameMaker. Remove the Steamworks extension before building, otherwise the build just runs the Steam game unmodified.

Known issues & limitations

If Steamworks is not removed before making a build, it will run the unmodified game on Steam instead.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game.

You need Pizza Tower on Steam; the Switch version will not work.

Features

The project provides an almost fully accurate decompilation intended for experienced people who want to mod without the code holding their hand.

Additional notes
