A very fun concept so far! I just wanted to let you know a couple spelling errors I noticed:

- on the explanation of the conveyor belt and the containers you say "The containers hold a smaller number of items than usaul.." usaul should be usual.

-On the endless mode, there is a spelling error where you say loose instead of what I believe should be lose (was clicking through the text boxes so Im not sure)

Other things: While endless mode could be fun, I wish if you got a perfect in every level you didnt have to do it. Also, Im not sure how this could be fixed, but I was experiencing some hand strain while playing. I am someone prone to hand strain so maybe others wont have this issue like I would.
