Very cool submission! Inventive yet logical puzzles, great audio and voice acting, and the script felt very well written, although it felt a tad rushed on the second half. The use of the pupper felt rewarding and intuitive at the same time.
At times it felt like the dialog lines were a little too close together, like a second or two of empty space between some lines might have made it feel more natural. I found myself paying too much attention to the lack of periods at the end of sentences and noticing all the other punctuation, something that slightly pulled my attention away from the experience, personally.
Overall, this is a very polished submission and it does feel like a complete experience, well written, thoughtful, and professional. Nice work!
