There are various items that can be pushed by David for credits. The best way to find these is to use David's Vision (hold
), these items will glow white. Just tap
until you no longer gain credits.
You can also push people, so push everyone you meet just to be safe.
Some places to check are the prologue (snowballs, signs and owl) at the lake.
In David's apartment (plants, lamp, squirrel in window, pigeon on the balcony where Amanda was banging on the door).
In Episode One, check the things in David's apartment mentioned above.
On the plane, there are various pillows on seats, and in the overhead compartments, so be sure to check all of those as well. Don't forget the toilet and flusher in the bathroom too.
On the plane, after lightening strike, push the air masks hanging from the ceiling, pillows and compartments, etc.
In Episode Two, push the stuffed dolls, garden gnomes, and animal carriers (these count towards the Zoologist achievement, which you should unlock if you pushed the squirrel and pigeon earlier).
Again, make sure you use Vision whenever you can, so you get everything. Things not yet pushed will be white, so watch for them, and make sure you go back to David's to push things in each Episode.
