Really impressive first entry! Lots of easy to use menus and nice audio feedback. Also, the music you chose really makes the game feel zen - although I did end up frantically clicking things after about 10 minutes cause I wanted that sweet cashola.
I'm not sure if there's anything that happens after you get the shop. It seems like it is all about the high score?
I tried getting a really high time on the windmill but it started taking off something like 10 seconds increments above a certain amount. But I had a great time anyway :)
Nice work!
