Really nice game! its really calming and the music is really nice!
Please dont add a quit button to webbuilts they serve no purpose and you can miss click on them, so it can get annoying.
And the wood background doesnt feat well with the other sprites, and some animations on the sprites would be better.
I think it would make more sense if you were polled to the light sources, like moths do in real light
so it would feat the theme better.
The game is really nice, and i enjoyed it! :)
