Good morning,  
I created a block game. Unfortunately 1 out of 2 times it gives me error 980 when I pass a level.  
Here is the link of my program:

According to the uber-handy [Makecode Documentation](https://arcade.makecode.com/device/error-codes)

> ## Panic codes
> 
> Some panic codes are for general errors that might occur while your program runs. Other times, a device or resource you want to use isn’t present or isn’t working and you receive a panic code for that. Several panic codes are related to the use of memory and accessing data in it.

A 980 error usually occurs when something related to using `undefined` goes wrong.

This topic also covers a 980 error.  
I’m not sure how much I can help considering I don’t speak French (perhaps @YuHayate could help with that?). Try using the debugger until you run into the error again. It should give some more useful information
