Very chill puzzle game with nice music. I liked the gradual introduction of different puzzle elements like the vents and the switches. It meant the difficulty kept increasing but at just the right pace so it never left me feeling frustrated or confused. Very nice art work, it all felt cohesive and really fit the game. The only thing that I feel would improve the experience is if the first couple of levels were tutorialised a bit more, though it didn't take me long to work out how to play. Overall this is a solid entry, and I enjoyed playing it! Well done for getting all this done in the time limit!
