Interesting idea here, and the first time I saw the night creature it spooked me, haha. It was nice seeing a 'cycle of life' game to fit the loop theme (I've only played a few), but also the day/night cycle even better fit the loop. I figured out the best way to move vertically was coiling up and bouncing straight up, but by then it was nighttime and I knew I was dead. I think my frames dropped a little each time I did it too, until the game was running at sub 10fps. It was nice you could kind of slither up vertical walls though, and I read the terrain was procedurally generated which is pretty cool for a jam submission. Nice work!
