That's awesome! I'm glad to hear that CH was able to entertain you :P
The hamsters are indeed pretty small on mobile - I'm aware of that. They were never intended for the mobile version in the first place. I added them back when CH only had the PC/Linux/Mac versions and left them in for the Android version because of player feedback. For anyone who doesn't want to hunt tiny pixel-sized hamsters, though, I've added a button to simply unlock the whole hamster gallery on mobile. It can be found in the in-game phone's hamster gallery, to the right of the phone itself.
It's not the greatest solution, but it lets people choose whether they want to kill their eyes looking for the tiny buggers, or just unlock the (optional) images and focus on the story.
