I tried your game, the art is really nice, and the music is calm and nice.
But i had to decrease in order to progress the game and see how the theme was implemented into the game. I don't know if it's a bug or a feature but I could collect sun only during the 1st day. The buttons for the suns was a bit clanky and even if i pressed them well-timed it seems to decrease my sunlight.
Overall, i would suggest a quicker gameplay and a little bit more interactive.
The idea is nice, I would like to see this idea be more polished into the future. Good Job!
Consider checking out our game too, and let us know your opinion :)
Give it a try or two...or more, cause it's hard!
