Very creative concept! The main idea for the gameplay's super original, the placing/destroying of walls is very smooth and the minimalist graphics work very well.

That being said, to me the game feels like it misses a whole lot of its potential. Some suggestions I have:
- The gameplay becomes very repetitive. Rather than constantly building on your old designs but just making them a bit longer, it would have been nice to see some other challenges to work around, such as unbreakable walls or just distinct levels in general.
- The time frame for being on time for the train is just a bit too small in my opinion.
- I think a speeding up button for the walking part would be very desirable, especially for the higher waiting times. Having to wait almost a full minute just because your path was three blocks too short/long is not very fun at all, unfortunately.
- My guy had a very free sense of physics - i.e., he was constantly constantly cutting corners and briefly walking through walls when it came to turns.
- You certainly  picked an... interesting song? But I'm really sure of dissonant salsa is the best fit for the game. Watching the guy traverse my maze for the umpteenth time with that music playing in the background made me feel just a bit like I was going crazy.

Nonetheless, the game is very promising, so good job! And hopefully my feedback can be helpful to you :)

Interesting concept, nice realisation

I spent a lot more time playing your game than I thought I would! I love the artstyle as well!

very cute game and great idea! you can be proud of yourself
