+# Tower Defense Game
+
+Unfortunately, this ended up very unfinished. Time management is a bitch, right? Anyways, to play, **move the `map` file from the game folder into your your `worlds` folder and use that.**
+
+KNOWN ISSUES I DIDNT HAVE TIME TO FIX
+- Junctions don't work
+- Turrets don't work
+- Enemies spawn, but don't attack or get damaged. Instant-kill from punching
+
+STUFF THAT DOES WORK
+- Resources
+- Cool custom hud
+- Mining and conveyoring ores into the inputs
