Level 13 and a superportal level have been released, along with a slightly better level select screen.

On level 13th, you'll have your first face-off with your most formidable enemy so far: a human. The following levels will keep this theme.

The next update will include keybinding and resolution options. For now, you can still hit alt+enter to play in a borderless maximized window.

This update also fixes the two boss-level broken achievements, and it kills the "Perfect level" achievements, because I don't think they're worth the time sink players have to invest to get them.
