+ * To-do:
+ * - Analog support
+ * - Some sort of connection control, it only sends packets
+ *   but there is no acknoledgement of a connection o keepalives
+ * - Send player name
+ * - Render something on-screen maybe a gui to configure IP and port
+     instead of the ridiculously long strings we're using now
+ * - Allow changing IP address and port in runtime
+ * - Support other platforms
+ * - Input recording / Combos
