Thank you! Happy to hear that others like the idea.
Noted on the limited tile variety. Based on the feedback we've been getting, as well as our own testing, we're definitely prioritizing improving this mechanic as well as making challenges in terms of completing a track.
We had fun making this game though! Even if we unfortunately had to shelve some of our more complex ideas due to the limited time, we're happy to hear that people are having fun with it and appreciate all the feedback. :D It'll definitely be useful in case we're able to revisit this and flesh it out further.
Thanks for playing!
