This was a fun game to playthrough and very tough to avoid hitting the porcelain lol. It reminds me of a claw machine game.
If you every do any future updates for this, giving the camera the ability to orbit the room while playing a level (Like with a claw machine, it would help the player line up a shot better), giving more weight to the anvil on movement and sways, and also giving the flies some sort of indicator on ground like a shadow decal to let player know where it is may help on night-time levels. (This part may also be solved with the orbital camera but just food for thought)
Also could throw in a dropping ability for smashing bugs on floor too. Just thoughts for future updates but again,
Great job on the game jam game!
