Some ideas I had that will be implemented sooner or later.
Dashing
The main mechanic is to walk around, pick up trash and interrupt calls. It may be a good idea to add a dash or sprint to the character, which gets refilled after picking up trash. This would add some more strategic factor, when to use the dash. And dashing is always fun :)
Content
The content is currently quite limited. But can be extended with more NPCs and more trash. Maybe even different stages / levels which you can clear.
Abilities
It would be good to reward the player somehow. One way would be single-use perks after picking up certain amounts of trash.
Trash amount
Perk
(every) 10
Recharge dash
(every) 30
Add throwable trash to inventory. You can throw it at people and interrupt calls
(every) 60
Phone jammer. You picked up enough trash to build a phone jammer which can interrupt all calls for 20 sec.
