 - Game comes with 15 levels right now.

+# Ideas to explore further

+- Using the github repo as a central level database, and fetching all the levels

+- Getting the community created content through pull
+  requests.
+- Making this project cross platform:

+- Find better solutions Level Selection and how it tries to rename every single
+  level if one of the in betweens are missing.
