Thanks for the feedback. I'm still a noob when it comes to Itch pitfalls like that, so it's good to know for the future.
Glad you liked the upgrades! I agree, games with a variety of upgrades are more interesting because it provides more of a strategy element (not that it matters much in the scope of this little game). To me, the more variables to tweak, the better.
I played for a couple hours after that. Mostly to completion. It's fun. If you put it on Steam the only suggestion I'd have is a toggleable 30 second timer in the upgrade menu that allows for autoruns or auto start the next day. I think it will get better ratings that way. The blue cats were my favorite. Both of them.
