I love the frantic pace of the game ! Shopping has never been so epic !
There are a lot of good idea, like the fact that you can just run across hallways, just keeping the mouse pressed to collect everything, with the sound design making it really juicy. The bingo card is also a great idea for the scoring !
However I think it lacked a bit of strategy, as the items on the shelves seemed to be put without logic, and it felt like the optimal strategy was to just brainlessly collect everything and pray for a good score. With some more level design and a bingo card that pairs well with the placement of objects, I think it could add some strategy without removing the funny frantic pace that makes the identity of the game.
I enjoyed that game quite a lot, I'd be curious to see what could be made with the concept. Well done !
