I mean this in the nicest way, but the game feels like a soulless version of Gnorp. There's not really any sense of progression, neither visually nor mechanically. So it's just numbers go up, and then you get a new makes-number-go-upper.
Taking Gnorp as inspiration, I feel like there really needs to be a sense of progression. I think having something like clicker heroes here might actually work really well. Progressing through different zones and feeling distinct walls will help a lot. Also Gnorp has builds, and I think that taking all these cool arrow ideas and getting to create synergistic builds that let you push further in a clicker heroes style progression system would actually give this game a solid identity.
I don't want to diminish the work you've done, as the game has a nice style and is clearly well put together, but the design is a bit lacking in my opinion... but I could see the game being really cool! If nothing else, it's reminding me to get off my metaphorical ass and do more work on my own game.
