Vibes are there. It looks really nice, I like the lightning, although I miss some post processing effects.
Audio - you mentioned there could be problem with it. There was no audio in the background, also no audio for gathering and spending the stars, what made the game hard to read. I didn't know when or from where I gathered the stars.
I like the idea of the game and generating stars from flowers. Gameplay itself is pretty slow, which fits the vibe, but I think the upgrades could be more often. For 2nd half of the time I didn't get any upgrades to buy. What in the end can make the player a bit bored.
No bugs.
Good job!
