Great Game, 5/5 so far. It would be cool though to see what you are upgrading in your house when you hover over the upgrade button for each initial purchase.
When tuning up your mower you can upgrade at higher levels before going for the lower ones without the extra cost. Get a few levels in each and then just save up to upgrade straight to higher levels.
I like how this game mirrors life. You date a guy for 30 years, then see a guy with slightly more ideal appearance. Then you immediately dump your boyfriend.
