Overall a very solid game! When I went through the tutorial and saw all the themes I thought it may be a bit overwhelming, there's so much stuff! But once the game starts it was pretty easy to see what's what. I like that the score carries on every week for the whole month. Normally with escalating score games the progress is practically reset, but here it's not and the items are still generating points, which makes it a lot more interesting. I also like that most of the sticker choices could also be useful for other themes or combos, and you don't need a minmaxed perfect week. But at the same time, the game felt a bit on the easy side, which totally fits the vibe so that's not a bad thing. I played through 3 months and the bonus/malus system is a nice touch.
The only thing I'm not sure about rating is the object inclusion. You could argue that stickers of objects aren't the objects themselves. But I'm not sure if that warrants a lower rating. I'll revisit it once I'm done rating all the other games.
Anyway, good stuff :D
