I love the art!
The gameplay is soo much fun, when the monster first spawn, i was like: Holly cow!
This game is hilarious! my highscore is 7482 points haha.
I'll mention what Asdonaur said: the colliders doesn't work very well: it's hard to select the objects, but not impossible.
I don't know if this was intentional but when the products are in the back of the conveyor belt, you can't grab nor scan them. It should be nice to be able to interact with them, because is already so much difficult in higher levels to track what you've scanned and what you haven't!
Very nice game, I like it very much, nice work!
