I find this really promising so far! It definitely captures the feel of Animal Crossing and is pretty fun to play.
Gameplay-wise, it's mostly solid and enjoyable. However, I do not like how you dump things personally. Turning the basket upside-down and having to push items to fall into the can is not only finicky, but you can end up losing an item or two. A possible idea I have is whenever you hold down the spacebar, it tips the basket diagonally and makes the items slide off the basket. One thing that would be nice is being able to exit out of the collecting game. Once you click "Collect", you can't exit out of there until time runs out, which would be a problem if you accidentally click it. I haven't come across any bugs in this area, but Mott's basket position is too low. You don't have to even dump the basket; the items just fall right into the can. Other than those things, it's definitely nice.
As for the pachinko machine, it's alright. It's just regular pachinko with a nice Animal Crossing skin to go with it. However, I came across a bug where I accidentally got two items in one run. Whenever the coin hit the wall of a REALLY big item, it ended up grabbing the item behind the wall also. I don't know how, but it did. Maybe try coding the items so they can fit whatever size within the hole. Besides that bug, it was functional.
Graphics-wise, it's okay. I do want to see more animation, like walking animations in the collecting game. With all the still images in this game, it ends up looking a bit rigid and still. The game does still look decent otherwise, and I honestly love the additional touch of changing the graphics once you change to a different music mix. It makes me happy inside.
Overall, despite the few bugs, I definitely enjoyed this game! I can't wait to see what other things you'll add to this game in the future. Please keep it up!
