I really like how you interpreted the limitation, the tiny pixel art is so cute! I think I would have enjoyed it more if the controls weren't mouse based as it felt really hard to navigate, which is such a shame because I really want to get further and see everything you created in the game! I wasn't always sure exactly what I was buying at the shop too.
I like the ambience, the cute chiptune sounds and the way the map isn't fully revealed :)
