I love the idea of "what happens when the player sleeps". It kinda plays on the old Toy Story idea, and I think there's a lot of potential in the game genre for that stuff too. That's what made most of the game fun. The art is also good, and the music is cool (I appreciate the volume slider in the title screen very much!) but albeit seemed unclear how it fit thematically. I think it helped make it seem more action packed for sure - it instantly made me aware of the rush timer.
I also appreciated that you could revive infinitely until sunrise - that made it less punishing to explore.
Unfortunately the collision system was a little frustrating sometimes (especially the rocks behind the plants), the difficulty curve was a bit out of order (except the start). And I didn't figure out exactly why the birds sometimes died when they touched me, and what the star did other than make creatures run away from me for a few seconds (my mind instantly went to Pacman where ghosts become vulnerable and run away). My biggest complaint was the second last level though - it seemed to just be long to add playtime but there was no challenge or things to do but wait until you got to the end. I would've quit if it wasn't because I really want to do my best to give feedback to other developers who might thirst for feedback as much as I do.
