Great game! Does the "Now Leave" mean leaving the game or just leaving the room in the game? Just in case I didn't understand it correctly.

Wow! This is a very, very cool idea! I love how you were able to get so much interesting gameplay out of a single room, and really it ended up being about a dozen different puzzles in one, which is impressive. Just when I thought I'd solved it every possible way, a new objective would pop up and make me realize there was more to this than I first realized.

That's great how put the tutorial and controls right on the UI, so the player never feels lost or confused. The movement controls are intuitive and easy to get used to. The objectives are easy to understand, and reminiscent of Portal where most of the puzzles are just about getting the box from point A to point B, with some twists thrown in. It's really nice having the instant-restart key, too - thanks for including that!

A minor suggestion would be to turn off the snap-to-stairs option by default (and maybe have a way to enable it in the menu), since I found that it interfered with my movement a bit when rushing to finish the 20-second objectives. And one other small improvement I might suggest would be to have the input/output pipes be different colors, since at the beginning I wasn't sure which yellow (open) pipe to deliver to.

All in all, this is fantastic puzzle game and I think it has great potential for a post-jam version or even an eventual Steam release. Great work on this! Do you plan to add more to it after the jam?
