Awesome progress! I maxed out all upgrades :) very addictive :)
1. The clicking is so satisfying now! I really liked the visuals and the autoclick upgrade! I wish you can max upgrades even more :)
2. I didn't noticed the health part tbh... And I didn't feel much difference in regards to item health. I noticed that they have different reward though. But my strategy was to maximize autoclicks first and then just click on the items in the water only.
3. Yes. It was clear and made sense. I would recommend to make them available at any time though :) When I had it available for the first time I didn't know how much I needed currency so I had only 19 collected but the autoclick was 20 - it was such a pity that I had to wait for another available upgrade... Also when the upgrades are available all the time I would feel more control over the build I am going for. Also, I would recommend to add some visual difference on the grades of the upgrade stars. like cupper, silver, gold... so each upgrade would feel more rewarding to have :)
4. Was awesome - first thing that I noticed and was like "that is so cozy"...
5. Yes, one small bug with visuals, sorry couldn't make a screenshot at a time, saw it twice during the play - I think when you open an item during the night when upgrades are opened it creates a visual artifact at the position of the item... maybe related to the splash animation... couldn't reproduce.
