Thanks so much for the feedback! I'm really happy you enjoyed my game!
The issue with the second level wasn't your fault - it was a bug I didn't have time to fix before the deadline. QwQ
But I finally found the problem today and have already fixed it!
I'll update the game after the voting period ends.
Also, thank you for the suggestion about S-curves and L-turns!
I've been wanting to add more track pieces too, and I plan to include them in the upcoming update.
Thanks again for playing and for your kind words - it really encourages me a lot!
