Firstly, congrats on your first itch game!
I think this game is very fun to mess around with. It's fun throwing the rod out there and just getting a cat, getting coins, getting a stronger rod, etc.
I did struggle at first with the shop and resetting! I tend to skip text cause I'm lazy so I didn't read that you needed to press enter to open the shop - instead, I just clicked on my coins and coin total, which I feel would be more logical to open the shop with?
It also seems like resetting the rod doesn't reset the velocity, which makes it hard to grab again when resetting. Using the rod also took me a little while, since it's more like a slingshot.
Still though! It's a fun game to mess with, and I can definitely see ways to iterate on it. Reminds me of games like Learn To Fly, in a good way. I also very much like the little tooltips when you catch a cat (they did seem to no longer appear after a while, though), if more species were to be added it'd be a fun indirect way to learn more about other species of cats!
