I know what you mean--idle games are so addicting. I've played them before and then looked at the clock and realised 30 minutes had passed!
I think the reason the pet upgrades wouldn't get purchased is because they use the 'treat' currency--the bones that the dogs pick up. However, the banners on itch block where you see how many of those you have, so it's kind of hard to tell. Didn't realise that until it was too late...
I really appreciate your feedback on the game. I definitely have intentions to address these, particularly in regards to upgrades and a prestige system. That along with some achievements I think will help with having more of a goal.
The quotes were there mostly to emphasise where 'The Munchies' are coming from ;) but I get what you mean.
I didn't even think of being able to pet the dog! Definitely an improvement that is needed immediately.
Thanks for playing and stayed tuned for updates. Also, there is a downloadable version that has a save file system...
