Really nice puzzle game! I love how the simple rules lead to such interesting gameplay! The art was also very well done, and the music fit the vibe. It felt a little weird to have the characters pop up when submitting but then not really saying anything of value. Another thing was the fact that the requirements don't exactly check what they say they do, if it says build at most 5 m^2 of entrance it still requires you to build some entrance event if it doesn't say it. Other than those little nitpicks it was really great!
