This is a really cute idea, and the artwork is adorable too. Gameplay-wise it's pretty simple but that made it a lot of mindless fun. Of course it did get way too easy after a while. But also when it's too hard it suddenly becomes unfair. You can upgrade your clownpi's mid-round but can't buy new ones, which doesn't do a whole lot to make you not feel helpless when a rabbit gets through your defenses. The most obvious thing that could have made this better is to have the rabbits in the immediate area clear out when the cake takes a hit, or have some other kind of way to be proactive once defenses are compromised. Besides difficulty I think it really needed some visual difference for higher level defenses, like a hue shift or slight scale increase (though idk how scalable those two are), it's a bit tedious to click on every one to see which has a cheaper upgrade. Anyway, this would be fun to see added to with more variety in its content!

Please, stop moon rabbits! The cake is a lie!
