I liked the art and pacing in the game. I understand wanting to reward players for winning with new characters, but I think it would have been fun to be able to choose more than one at the beginning.
I came first but still got game over, so there may be a bug there? It's a shame about the netlify watermark... you should be able to host directly on itch.io - although that may depend on game engine

That's nice, I liked it. Taking first place turned out not to be all that easy.

Nice game! Congrats on it! I don't know what happened at the beginning, but in the first 2-3 races I didn't get the story. I was pressing X to choose Alex but nothing was happening and then the race would start. Only on the 4th time I noticed the dialog. Which is a nice touch to the game. And, at times the game can start to feel a little dull. As someone suggested, maybe add some power-ups on the track, or maybe more obstacles. Anyway, the idea to build up the speed seemed interesting. Congrats on the game

Kinda ironic that the story of the game is about an AI taking over and the game itself was built using AI XD 
Edit: Just read the comment bellow and saw that it's not the case.  

It's a nice game overall, has potential for sure. 

Good points: 

• the art is really well done 
• There's a narrative. 
• It is a good take on a racing game. 

Bad points: 

• I found that sometimes the collisions are a bit janky... There was more than one time that was clearly not on the sandpit and my car slowed down as if it was on it. 
• For some reason, I always get a game over, don't seem to matter the place I finish the race. 
• I am not able to choose my character, always only having Alex as an option. Is there a reason why?

The game is a lot of fun, and I really like the different weather and environmental effects, such as night and rain. The only thing that might be a nice addition would be a few power ups that you can pick up along the way.

One more question about the development process. Did you let the AI do the coding while you made the graphics yourself? If so, what was your experience like? Did you have to step in and correct things often, or did the AI usually get the code right on the first try?

Good game and well paced levels.  Must've been difficult to balance the opponents and obstacles to help the player.  I ended up getting 2nd place overall and it seemed like I got a "good" ending.  Are there multiple endings?  I think the rain could use a little work because rain doesn't just fall straight down when flying straight.  I think they'd be diagonal streaks... or speed lines that come and go could also be nice.  Anyways, well done.

Good sprites, but kinda monotonous gameplay in general and although is interesting to have a narrative, as far as i saw the narrative dont fit all too well with the gameplay.
