That is a very nice game! I love everything about it - and I normally don’t play idle games :)
It is small and simple, can run on a slice of bread, it has a dark mode, it doesn’t need registration, just enter and play :)
Suggestion: I am a fast reader, so I found the „tutorial“ (if you name it that) very fast. Other players could overlook it, though, so maybe you could make it stand out a bit.
And if you ever think about translating it: I‘m native German speaker with very good grammar knowledge (even for a German). I would like to give back a bit.
