This is the third jam I've seen this submission in.
Really cool game, if felt great to play.
There should be a button that says "Next Level" that appears in the middle of the screen. To be fair, it isn't super clear that it is a button. If you reload the game that might fix it too. Sorry for the issue.
The moving platforms are a little janky but other than that it is a fun platformer with a charming art style.
