Subject: [PATCH] gnu: Add the-powder-toy.

From: Timotej Lazar <[email-masked]>
Date: Sun, 31 Mar 2024 16:15:13 +0200

* gnu/packages/games.scm (the-powder-toy): New variable.

Change-Id: I4c11fa48ef2b92222029e082d472c8157eb1f25f
---
This adds the Powder Toy 2D physics simulation game. Most of the package
deals with installing resources because the install target doesn’t. The
desktop and related files seem to function OK after installation.

Thanks!
