First of all, why did you submit a game that has AI-generated assets in a game jam where that isn't allowed? And, secondly, why did you only admit to it when confronted? Were you trying to pull a fast one? Were you hoping that I wouldn't notice?
Secondly, you know that you could have just used third-party assets for the background too, right?
Also, I'm going to require proof that you made the repairer asset yourself, considering that you've lied to me by omission before.
