Thanks for playing the game! and your feedback. To explain a bit, the weird sweeping is part of the game not you being bad :), if you cross too fast with little strength you leave the trash behind if you sweep to hard you can knock of some painting :P, still not clear enough for the player so is natural you felt is just a bug, but we liked the feel of it(it happened naturally), so probably gonna work more on visual feedback in the future so is clear and solid dynamic
