I actually really like this one. It had a really nice, tranquil, meditative quality, and the fact you have to collect milk added a nice little bit of extra charm.
I ended up walking to 511, then, accepting all things must come to an end, sat my white box down under a dead tree, and waited for starvation to set in.
What I think you did exceptionally well: You assessed what you can and can't do, what assets you have, and provided a great, cohesive experience for a first game made in a week. That ended up creating this actually really relaxing and meditative experience.
I hope you had fun making this and will continue to do so on your dev journey :)
