Visually, it's right up my alley! The visual and audio atmosphere is well done, especially "the day to night" transition, which I think is super well done.
Gameplay-wise, it's simple and effective. Contrary to what some comments say, I don't think spamming the sun to skip the night is an issue, but I would've liked some feedback like the sun growing bigger as you spam ( and maybe light the scene a bit) to give the action more feel. The game also starts a bit abruptly before you even finish reading, which makes things a little hard to understand on your first try.
Good job ! :D
