A classic TD game, this really brings me back to the days where I played Bloons Tower Defence!
The game is a good experience all around, it feels polished for a 3h project and it is what you would expect from a TD game 😀
However, I don't really see how it fits in the theme, I understand that you place towers at daytime, and the rounds are at nighttime, but this day/night cycle feels like a re-skin of a basic mechanic of the TD genre itself instead of a mechanic of its own to fit well 😬
However, the rest of the game is great, good work! 😁
