+A somewhat upgraded/refactored version of NXEngine by Caitlin Shaw.
+
+NXEngine is a complete open-source clone/rewrite of the masterpiece
+jump-and-run platformer Doukutsu Monogatari (also known as Cave Story).
+
+Differences from the original version of NXEngine:
+  * Port to SDL2 (thanks to PIlin)
+  * More resolutions and proper widescreen support up to Full HD
+    (thanks to EXL)
+  * Animated character portraits
+  * Modern main menu
+  * Credits graphics specific to the Mimiga Mask ending
+  * Localization support
+  * Force feedback support
+  * Custom soundtrack support
+  * Initial mod support
+  * Vita/Switch versions
+  * Cleaner and partly-refactored code
+  * Tons of gameplay-related bugfixes
+  * Removed built-in data extractor
+  * Removed replays, as they were buggy/not implemented anyway

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
