What a cool game! I was confused at first (maybe because I haven't played incremental games before), but then the game sucked me in.
It didn't make intuitive sense to me that building a higher tower does not consume resources. But as I kept playing, it just worked. But I was a bit confused for a while.
Also, in the beginning, I had this feeling of "what am I even doing here" and it didn't feel like I was making any meaningful choices, but that went away pretty quickly as the game started progressing.
The visual style is really nice and I liked the music too. Graphics could be a bit richer and maybe evolve even more as the game progresses to make the game feel more rewarding.
