I felt bad about your build issues, so I ended up looking at your page and playing the web version, I'll give a bit of feedback on that so you get some ideas for improvement.
Your art is nice, the assets work really well together! You've got some issues with collision, I don't know exactly how you implemented them, but I've got the feeling you put the movement in the Update function and not the Fixed Update function (fixed update is generally used for movement/physics). For gameplay I'd suggest adding a tutorial and making it so the balls can be put into the trash can all at once. Overall, for what seems to be one of your first games, I can already see some potential, hope to see your work in future jams!
