Nice press your luck mechanic with the gun size vs recoil.
When I played cold, I didn't understand if there was an objective. It wasn't clear to me what the pickups did. It seemed like a collectathon or "find the macguffin", but when I looked at the game page I discovered it was: survive 3 minutes. For your next jam, maybe lean into that design decision and make the clock really obvious to the player. Or make the purpose of the pickups much more obvious.
