Your todo comment section is somehow causing your troubles: ![Screenshot 2023-10-03 at 21.44.54](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/2X/e/eeb7773f944b462f11e9b3c998f83c5ebe2a5c16.png) Remove it, and - voilà - your code converts back to blocks: > **[MakeCode Runway Mario](https://arcade.makecode.com/01940-99643-29625-32136)** > > Made with ❤️ in Microsoft MakeCode Arcade. ---

I’m guessing that’s because the compiler gets confused with the multiline string, because that’s the only way you can write comments in python. It doesn’t know how to convert that to blocks ---

@Sarge we do actually handle free floating multiline strings in python! They get converted into multiline comments. We just don’t handle certain emojis, apparently. If you delete the emojis the code should convert cleanly. ---

I’m having this same issue, but I don’t know why. All I did was switch from blocks to JavaScript and back. Here’s the project: > **[Arcade!Funkin' Engine 0.1.5](https://arcade.makecode.com/S04598-57013-49381-50578)** > > Made with ❤️ in Microsoft MakeCode Arcade. ---
