For those who wish to play this mod on Android devices but suffer from the stuck of escape system and the undisplayable CGs in the menu, I made a patch to this mod using ChatGPT, it replaced some functions rely on NW.js environment into compatible formats with basic NodeJS, I tested it on my device and it seems works fine, you can try it. Just replace the original game files with those contained in the .zip file, but make sure you backup all the origin game files, especially saving files, before you doing anything.

Just make sure you play it with MTool (a emulator as well as a game modifier for Android), this tool contains GeckoView and NodeJS environment inside, and it implemented many NW.js functions, thus it yields a better compatibility with those games that rely on NW.js than other average emulators, such as JoiPlay. For a game like Didnapper 2 and a Mod like Overkill that both relies on NW.js, using MTool should encounter less bug than using other emulators.
To be noticed, I only tested it on Didnapper 2 v1.2.4 + Overkill v0.14.4 , I can not guarantee that it will also works on other versions of Didnapper 2 and Overkill Mod, but the general idea is to replace NW.js functions with compatible NodeJS formats, so I suppose you can easily make another patch for other versions of Didnapper 2 and Overkill Mod with ChatGPT or Claude or whatever LLM tools you familiar with, vibe coding certainly are convenient these days.
