While I enjoy the game, I do think that there are some things that are lacking. For example, it took me a while to realise that the conveyor belts don't work, and that I needed to push the packages into the belts. There is also the lack of music, but for a jam game I can forgive that. Also, instead of having to push a certain number of packages to the right conveyor belt, why not make it a game where you just push the packages into the conveyor belt, but if you get 3 wrong you lose? I don't know, something like that.
Still, I had fun! It didn't blow my mind and make me rethink the way games work, but it was a good little time waster!
