I love the idea. At first, I was very much not sold on the idea of a platformer without a jumping as that is what the game most reminds me of. But the combination of platforming and puzzle gameplay makes this game really shine. I love the overall aesthetic too, its quite charming. For the specific feedback, I think you actually nailed it with the tutorial. I found it very easy to follow and it taught the mechanics well over time. If there was any improvement to make, I would say it would be to add more of an indicator to talk to the professor guy in further levels as I was confused at one point because I forgot to talk to him. That's mostly on me but might be better to beat people over the head with it. Really fantastic game on the whole!
