Fun premise, and the sack slowing you down as it fills is a nice greed trade-off (the 98% Speed pop after the first doorbell sells it). The How to Play page is clear too.
One input bug, reproduced 3 of 3 times on your live page at 1366x768, and again on the newer build that's up tonight: if you're holding a move key and the browser focus leaves the game (I clicked the itch page beside the frame) and you let go there, the game never sees the release. The kid keeps walking with nothing pressed: once straight down the open street for 4+ seconds, once into a parked truck where he stayed pinned. Clicking back into the game doesn't stop him; one tap of the same key does. Since the sack fill and snatchers punish wasted time, that one can cost a run. Releasing the move actions on focus loss (NOTIFICATION_APPLICATION_FOCUS_OUT in Godot) should fix it.
Small one: the itch jam badge column sits over the top-right of the frame at 1366x768; fullscreen avoids it.
