I'm happy to hear you liked it!
The level editor kind of came accidentally, as it was the easiest way for me to make levels for the game. I just had to make it a bit prettier and add some extra UI, and it went in the final game. Due to some security stuff on itch.io, you can't copy/paste level text into the game directly, but the windows and android versions allow you to encode/decode levels in text form and share custom levels. Here's one, for if you happen to have used one of those versions. (make sure not to get any leading or trailing spaces) Otherwise don't worry about it.

Either way, thank you very much for your comment!
