+        <p>Tem here!!! It's my first time making an RPGmaker game!! Its my first time trying to put together my own project outside of an animated thing (though... I guess this is still sort of.. that..).  I've always wanted to make an RPGMaker game, though I guess it isn't much of a game. Its around 15-20 minutes long (though I guess it could be longer if you try to get all the endings).</p>
+        <p>There's around 4 different endings you can get.</p>
+        <p>A small warning that one of the endings is a little creepy/unsettling.. But hopefully its not too much.</p>

Steps to build a flatpak from Escaped Chasm

Right, before you begin:

This diff applies to the Escaped_Chasm folder within the Escaped_Chasm_Contents folder, referred to as the "game folder" below. Yes, you can indeed apply a diff to an entire directory. Cool, huh?

Prerequisites

• Escaped Chasm for Windows (whichever version)
• Node.js and npm
• Flatpak (duh) and flatpak-builder
• From Flathub, org.freedesktop.Sdk and org.freedesktop.Sdk.Extension.node12

How to

• Run dos2unix package.json in the game folder in order to apply the patch.
• Run patch -p1 -ui chasm.patch in the game folder, usually Escaped_Chasm.
• Run npm install in the www directory. We need the node_modules in there.
• Run dos2unix www/js/rpg_managers.js to change the line endings in that file, we'll need to patch it. You'll get an error otherwise.
• Then, run flatpak-builder build mybuilddir io.itch.tuyoki.EscapedChasm.yaml.
