Thanks a lot for helping out! I actually gave it another shot a couple hours after my post myself, and I figured out what I did!
It was only day 2 so I wasn't used to the game yet, and I ran out of the garage before the I could tell that the cans inside were pink (the white crossfade obscurred it, and I ran out before it fully transitioned). So I just wandered around not seeing anything colorful, wondering why none of the trash cans were doing anything at all.
When I tried it again later, I noticed the colored cans right away inside the garage and was less confused after having more of a chance to understand what the game even wanted from me.
Anyways, I wasn't going to make a video of it, but I may if you wouldn't mind? I can't say it was exactly 'fun' or something that'd be that entertaining to watch, but it is for a sure a positive message that people should see! If you'd rather not I'd understand, I notice your payment model and whatnot. Either way, congratulations on the Steam release, you guys deserve it!
