I'll answer here instead of the google form.
I finished it in about 20-ish minutes.
It was pretty clear what trash belonged to what bin.
Clicking felt fine, obviously as things disappear, where you were clicking might be where trash no longer is, so that's part of any difficulty the game may have, completely understandable.
I feel the money should show up next to the cellphone on the map, and in the top left with the money symbol like it does everywhere else when you're on the shop screen. The money though kinda didn't make sense to me when the legend tells me that 100 trash=$40, but there were most times where I made less than that and it told me I picked up like 200 trash items. In fact the first garage told me I made negative money, even though I bought only one item.
There was one interesting glitch, on the dump and another level, randomly, I got a phantom bin just constantly waiting at the beginning of the row of bins, it did nothing, just was there as a glitch, had to make sure I paid attention to the bin before to know what I was actually suppose to be sorting. Not sure why it happened, nor what triggered it.
Other than that, I don't know what the items or cassette player does. Guessing the museum isn't ready yet. And I dunno what else to add. Maybe more trash variety?
Hope this helps ya and this was a one and done for me. Good luck to you.
