I love how it's almost like a mix of a tycoon and a tower defense style game. The artist's work is fantastic just like in the last jam and the music is nicely made too! I do have some suggestions and critiques though.
First I'd recommend setting a much smaller viewport for a web build, even if the intended way is to play in fullscreen. Most probably switch to fullscreen anyway but when the viewport is this big then the player has to scroll to get to that button.
I also don't think I saw any way to replace or remove things from tiles. I did see the message about how you can't remove roads which is fair enough but as for the buildings and flowers, a way to replace them would have gone a long way.
Still I did have a good time with this and with a bit more polish it could be a good time waster!
