This is a fairly fun game, and the concept is on point with the theme. Waiting for the right moment to harvest is a fun game dynamic in itself. Good stuff!

Here are a few suggestions I have if you plan to revisit this:

You might be able to make the earlier levels bigger on screen, so they don't feel so small. (However, that does mean your mouse would have to travel further to reach the next mushroom.)

Perhaps replace the timer-based fail condition with a threshold meter? I would rather see the room overflow with mushrooms due to my own failure of not harvesting them fast enough, rather than have them automatically fill the room when time's up. You might communicate this with a visual meter, accompanied by some neighbor dialogue bubbles at certain points, with messages like "What's that smell?" and "I think there's something going on with the neighbor." to "I'm filing a complaint."

The sound effects are great; consider adding some fitting music. ;)

Overall, nice entry, and good luck!

This has a lot of potential to be a pretty fun puzzle game! Figuring out exactly when to start harvesting is fun, but I wish there was an easy reset button.

Really fun and simple, its great!

What a cool concept, it really fits the theme ! It's fun, it would be fun to have more mechanics (like differents mushrooms or gardens with special properies) ! Well done !

Very fun and very simple, I love it! I would suggest adding a restart button as I clicked the mushroom right away and was confused as to what I needed to do while the timer ticked down. Overall very smooth gameplay with a clean presentation, very well done!

A very interesting concept where you have to determine when is the appropriate time to pluck the mushroom before it spiral out of control. 

Quite a patient game you made here! I can see that this could be useful for mobile application!

I  instantly lost at the first level and I laughed hard as the shrooms overwhelmed my screen, well done!

However, I had some trouble clicking on the shrooms because of their size and the speed needed.

its a me mario and luigi. This'a was a lot of fun. Im a big fan of mushrooms and loved this'a game a lot. I couldn't help losing a couple times just to get a lot of mushrooms!

Very interesting game. Possible the more creative one so far. It also shows very well the dangers of exponential growth, fits the "out of control" theme as well as our current situation in the world.
