The different units and animations and sounds were all so so lovely! Especially the reference to a musical scale is an insanely creative take on the theme that I hadn't seen until now.
It was a bit opaque how I acquired new funds and what the differently-colored health bars meant, but apart from that, the game felt lovely and polished. Also, the quit button being "im 2 scared" and just the language of this entire package was funny and adorable :3
