fun tower defence. maybe add some quality of life improvements like: hotkeys for buttons, upgrade multiple or random towers that are not upgraded yet.
towards the end on day 8 i got a fox on daytime side but got still killed.
its bit hard to select squirrel nests maybe make the selection area bigger.
towards the end I got so many creatures going all around that it started lag the game. maybe don't add all the animals going around on daytime, limit the amount to reasonable amount visible. I got so many bird and squirrels. :D
I got to day 12 and it become so laggy I couldn't go any longer.
Good job on the game jam!
