Really happy you like it! <3
The squirrels only trip you if you're going near max speed. If you tap the button and slowly walk past, they won't trip you.
Ah! Do they only trip you when they're moving, or always?
Always. Sorry it's not really explained anywhere.. It's hard to fit fine tutorial details in that tiny resolution.
Probably already figured this out, but fountains trip while you're in the air.
