Nice little game. I don't see the theme or the  girly aspect of it, though. Also, I've reached a state where my mold stopped generating income and I couldn't feed it. I don't know if that's a bug or I won or lost. Lol. A little explanation about how the temperature and water work would be appreciated. :)

This is an idle game but I'm not sure how to  make progress. I see that I have income but don't see a way to increase that income, nor is there any goal or progression. 

Wow I was not expecting to see a mold idle game xD! Some simple color swaps instead of brown/black/green would help it be a little girlier ~ Maybe some decor. I think the game mainly needs juice for more satisfaction. More feedback with number popups, larger UI elements etc. 

i dont personally see how this is in theme, but otherwise, simple game, pretty nice idler, although it takes a long time.

I'm not really sure how it is girly, maybe you could add some clarification in the page description :)

Feedback:

Consider moving all the UI like the shop, cookies, temp to a side panel, that way the player will not look back and forth between the corners. Maybe add the grow rate in that panel as well? so that the player could know how much progress every action makes. It would be nicer for the player to get +0.1 cookies every sub second, other then wait for a few seconds and get +5, I think it will make the game feel more alive.

I assume the goal is to grow the mold over the whole black area?

Consider speeding it up a lot, maybe add a timer at the end so players could compare speedruns times. give is a bit of replayability.

Nice gameplay concept. It's cool to see the mold grow. The first too stages are too slow in my opinion, maybe need some speeding up. I found no bugs.
