Thanks for the feedback! But part of the point of the game is to make that progression faster by fiddleing arround with the "toys" and figuring new and better ways of making poop, so it was quite intentional for it to be a lil slow.
If you missed out some of the "secret" interactions, there's a comment at the end of its page with some of them (and some strategies to make and collect poop faster) if you feel like checking 'em out! :3
