Thanks. Fantastic game. I have send you a small donate. I'm in level 20. One disadvantage - game doesn't save progress in cookie/local storage and I can't close tab. I afraid of F5 key ๐
I have allowed cookies (and local storage) from domains rob1221.itch.io and itch.io but Chrome says that have blocked third-party cookies.
I saw that you save game progress and settings into ssl.hwcdn.net key. When I have enabled them then game save works OK ๐
