As usual, really nice game! Lots of polish and content, and I enjoyed playing it :)
Like others said, it wasn't clear that I was able to click on another mushroom (although it says it in the game), and I don't think a tutorial was needed tbh; I feel it's simple enough where you could do without, and it'd feel better imo.
This definitely fits the theme, and the art and music were really great!
The only other piece of feedback I have is that maybe 80% of the games do this exact thing (which is fine), just maybe I would've liked a more creative take on the theme. Saying that, this game executed that idea the best (from what I've played) and I had a lot of fun playing it!
