Thank you so much for playing it! I'm so happy you enjoyed it. Yes, I absolutely agree with the day length (especially when you are trying to water flowers on the outer edges of the park) and a "make day longer" upgrade was definitely in my original design doc but I just didn't get around to adding it too the prototype...
I very much plan to keep working on the game so keep an eye out! Currently working on an update that fixes some of the outstanding bugs I didn't get too before the contest and adding native controller support. Just getting some of the ground work out of the way so I can get to adding more content!
