Play and tinkering
These are the tutorials I found on youtube, however these are only those I found worked for me. I had a really massy experiences cannot work, which cause my frastration on coding and scripts.
For the theme "play and tinkering", I think I need to make something which people can keep doing different approaches and also have fun of it. I first thought about to make a running game and player need to dodge obstacles., but I think this is too common and I want to find something new.
Then I look to the click game, which clicking one item and count the amout of clicking, but I also think this is kinda boring, so I want to find a way to make items spawn randomly and player need to click on it to destroy it，which is like a reaction game. But I have looked at a lot of tutorials on how to create and destroy the item, I could not found an appropriate one for me, and scripting by myself still too difficult for me, so I just learn how to spawn items on click.
Once the outcome completed, I look at it and think about how to make it more fun and visually pleaseful. I then consider to make an animation on the sprites. Also drew a nice looking sprite by myself. Hope this can be a better response to the play.
I think the final result seems nice, but still have many potential to make it better. Like the background, maybe I can make a better look background to provide more hierarchy on the visual presentation, the sprites created by click may could also be animated, but I cound not find a way to do this now. Movements of the sprites can also be considered. It also could destroy the sprites fall outside the screen to decrease system pressure. But for now, I think the outcome performance pretty well, while I just started unity, there are more possibilities and potential if I excavate the program more.
