This was a good idea, and had fun playing this one. The music is also good. Here are some things i think could be improved:
The graphics were a little rough. Especially the grass. When i tried to catch some fish, i approached the "pool" and i couldn't properly see the letters that i was supposed to write. The text on the floor isn't probably the best place, and the UI overall could be improved.
But i think that what you have achieved in one week is great and i enjoyed this one.
