I really, really, really wanted to enjoy this game, and I spent way longer on it than I meant to because there's a very neat core concept there, and I enjoyed the writing! But the interface needed a bit more polish (clicking and dragging belts was a bit too sensitive - I had a lot of trouble drawing straight lines, and also I wish you could edit the contraption while the pizza was paused because having to kind of remember where the pizza ended up was really annoying) and there were some bugs (for example, if you ever accidentally stacked two pizza slices, that's just on the board forever now, and if your pizza ever touched the bottom or top edge, that made it not go back to the starting position and you had to go home and then to level select to start the level over) that made the game kind of frustrating. Also, I solved level 4 without needing the tips, meaning I never learned that grabbers were the intended strategy, meaning I spent forever trying to solve level 5 without grabbers before realizing that using a grabber was required.
With a bit more polish though I could definitely see this being a really addictive game, since I couldn't stop playing it despite the frustrating elements.
