I like this! It would be good to have a bit more of a heads-up when the night is about to end (since I can't watch what I'm doing and keep an eye on the moon at the same time), and I found that sometimes I couldn't collect an orb without moving off it and back on again, but for three hours this is fantastic work! It's got a great look and feel to it.
Ah thanks! I did originally have almost every sprite on the screen more gradually fade to night and back into morning (to better signal the change AND fit the theme more) but I couldn't get it to work right within the time limit:( I also messed around with different sounds and all, but nothing came together in time either. Glad you had a chance to play it through and thanks for the feedback!
