I sometimes wonder if the AI generator was involved in some of the simpler GDevelop jam games, but in this case I don't get the impression that it was. My brief experiments with that thing have led to games that feel technically competent to a certain extent (with coin pickups featuring variably pitched sound, etc.), but that have nonsensical level layouts and poor balance, etc. This seems much more like something built from the ground up (hand-drawn art, but no camera movement and no sound, and the UI occasionally hidden by bits of the level). Basically, I'd be more suspicious of games that are only superficially polished/complete than ones that feel unfinished in a more rounded way.

Ah - if I understand correctly (relying on Google Translate here) then this might not actually have been a valid jam entry in the first place. I think the games are supposed to be new, made specifically for the jam theme. (But yeah, now that you mention it, the March 2022 release date is a pretty firm indication it didn't involve the AI game generator I'm pretty sure was only added to GDevelop a few weeks ago!)
Apologies for replying in English, by the way. The only way I could write in Spanish would be using automatic translation, and since you've managed to read previous English comments I trust you more than Google!
