Not a bad time sink :-) I like the graphics for the munchies, but I was a bit confused by some of the upgrades. Some of the upgrade mechanics seem to be broken. I got the 3rd dog at 625 and it said 3/3, but it updated the next price level as though there was another pet available. You might have some performance issues too. I noticed it kept sticking.
I see some other comments mentioning sounds, but I don't think it works on the WebGL version. It's probably related to where you're storing them (the resources folder?)
Good to see you're continuing the development. This kind of sticking power will serve you well :-)
