The music really fits the game well, with the nice chill setting in the beginning then the rougher guitar track when things switch up. The plot twist is really cool and innovative - I love how it starts off as a city building game then suddenly turns into a tower defense.
(also like the "A nice friendly snowman!" tooltip when you buy snowmen... ha.)
Might be cool if you could sell buildings, so you could replace houses with banks or rework your setup as you progress. Also slightly strange that there are non functional houses already on the map when you start which look about the same as the money-generating ones you place.
Overall, great game! Pretty enjoyable, good job :) Also the little snowman hats that fall on the ground for a little bit when they die is a nice effect, and the extra dialog when you keep clicking after winning lol.
