You have a pretty good base of a game here but I think it could use some work. I think just a few small changes could make this a really solid game!! The tutorial was a little scary and confusing at first but once I actually got into the game it just clicked in place and I understood it pretty well!! Didn't take long to wrap my head around at all besides from a few things.
It took me a bit to understand how filling the biscuit bags worked. I wasn't sure if I was supposed to fill them completely or if I was allowed to mix different biscuits together or not. I eventually just stopped mixing different biscuits and only filling the bags more if they asked for more than one of that item. That might be on me, though. I do have severe dumb brain. I wasn't exactly sure what meant I did an order right or wrong. I assume the sort of -.- faces the little guys do means I got the order wrong. The sound queues made me think I got it wrong no matter what for a bit haha. I think the camera moving the mouse around is a little unnecessary, everything fit on screen with no issue and it made me a little nauseous. Coffee and the water for tea both take a bit to fill, which I don't mind I think that can work, but it did make me think I broke the game and it wasn't reacting to my inputs for a bit. I think if you added an animation to show it was pouring it that would work, though. It would be nice if it either crossed off items you've completed or the items you put down on the counter showed up on the counter, this isn't too much of an issue I didn't find myself forgetting what I had done at all and you could argue that this is part of the challenge but it did make me unsure for a while on if I was actually giving the characters their stuff. I also kept accidentally picking up plates and paper bags by accident and I wasn't sure how to put them down.
Some of the biscuits and teas are a little difficult to differentiate, could either be a positive or a negative depending on how you look at it haha. It wasn't impossible to get them right at all, though.
I feel really bad for having written all of that but really I don't think any of those are big issues, it's just a bunch of smaller issues with (I think) simple fixes that rack up and get a little annoying altogether.
I do like the premise of the game, it's simple but really sweet. I really like the little guys that change the gameplay in some way like that one guy (who I assume is doᗺ) that makes everything reverse and the guy who makes everything blurry. Adds a slight extra challenge and throws you off your feet just enough to keep you interested in the game. Even though they didn't change gameplay the little guy with the skirt was also really cute :) that one's my favourite.
This is probably more of a personal thing, not a super big fan of the aesthetic. I expected more deep purples and more obvious space related things based off the menu and thumbnails. The colours in the game feel more like silly kids game than something cozy to sit down with a cup of tea with. Not a big issue at all, it's fine, doesn't matter, and I get that colours can be a little tricky arghh scary hard to get right in art. I do really like the designs of the little guys regardless, though, and they do fit in their environment!! The style is consistent which is more important than personal taste probably, haha.
I played up until I got the end screen! Huzzah! I can pay off my mob debt! That caught me a little off guard but I'll assume that's a place holder for the jam or something, it gets the job done. I did play this with a cup of tea and a gingerbread man, and I think they paired very nicely with the game! :)
