Good job submitting a game! I really love the house designs, I spent a lot of time trying to get different combinations to see all of the different houses. My favorites were the upgraded Mine house and the stone tower. The final splash screens were really well done too, my favorite was the underground city after the "dig dig a hole" ending. My one wish would be for an achievement log to show what houses and endings I've achieved so I knew how many I had left to discover / give me a little more direction on what combinations I should try. Great job with the music too! And I like your take on the upgrade theme. Thanks for participating!
