+- patch `upload_level` to use 2.2 unlisted (friends only stuff)
-- add level parsing (`upload_level` can use the correct `length`, `objects`, `coins`, and `two_player`)
+- in our level parsing, check for dual portals rather than just starting dual
 - <small>green name users...</small>
+- maybe tone down the clone usage (this is for sure causing memory problems 😉)
