Excellent work. Story setup was awesome and the temperature mechanic was done super well. Animations and backdrop were all gorgeous. 1 bug I ran into, you can clip into the bats if you jump on them while they are near the ground (tough to repeat but was able to do it twice). Also, was very hard to progress in last level with bats since they don't stop chasing, had to cheese them away to progress. The bat AI might feel more intentional if you limit their area and create an "idle wander." Great job and excited to see this expanded on if you choose to :)
