Love this game! This is the most unique game I have played so far. The way you included mistakes in the finished quilt and framed them as a good thing was so cool. I liked how there was a pattern to the individual quilt squares. I also saw your discussion post about how you added the draping effect at the end and it turned out great looking!
My suggestions to bring this game to the next level would be to not always include the house in the upper right corner. Adding the house makes the quilt creation part smaller and more difficult to use with a small screen and poor eyesight. I wouldn't completely get rid of the house because then you can't include the cute part at the end with the quilt draping. I would add a start and end scene where you can pick the quilt you would like to make and drape the quilt instead of having the house visible all the time. The quilt pattern also moves while you are sewing, which was a little jarring.
Again, this game is very unique to me. You were smart to come up with this Tetris quilt idea and nailed the coziness. I can't wait to see what you make in the future!
