Thanks for giving our game a try! We didn't have the time to make a tutorial, sadly, so it looks like the game turned out very confusing. For example, the second house is a whole scale smaller than the other house (anteater VS elephant), so you need to select another tab in the items catalog to find furniture that is the correct size. There's a (small) text on screen saying "this house is too big" or "this house is too small" when the size is not correct.
But yeah, it's definitely VERY confusing. I'm super happy that you loved the art anyway! Thank you again!
