Gamification as a playful and motivating educational experience	MDE	55 from 65, 87.3%	I loved how this subject has been proposed. Because I’ve had a great time doing the challenges. (E 3) The activities, such as the pill, creating the video or the challenges of the companions were a way to see your companions in these moments and have a fun time. (E 17) The escape room has been very cool, not only because it was the first time but because it has kept us totally in tension until the last moment. In the end it has been the finishing touch of the subject, a clear reflection of everything lived throughout the semester. I can only say, thank you. (E 21)
	Motivation	60 from 63, 95.2%	[I liked it] a lot, because the teacher has raised it in a very bearable playful way and without any pressure. It has made us like it when doing the internship, etc. (E 40) The activities were entertaining and motivated me to learn much more. (E 68)
	Fun	59 from 63, 93.6%	I liked it very much since the subject has been raised in a very dynamic and playful way in which the classes have not bored us. (E 28)
	Active methodology	60 from 63, 95.2%	There have been many activities that have allowed us to develop in an entertaining and practical way the contents of the subject. (E 3) I found the approach super dynamic, nothing heavy and even fun. It gives a place to theory because it must have its space, but also to practice and dynamism. I personally love working with practical things rather than just having theory, a good mix is key. (E 19)
	Different from traditional education	19 from 63, 30.2%	I loved it, because it is not the traditional approach that the rest of the teachers follow to put some slides and explain them, that in the long run becomes boring and monotonous. With this approach, through the activities we have been doing, we have learned the contents of this subject in a more enjoyable and fun way. (E 25) Super profes has been totally different from the other [subjects] and I think that all teachers should rethink making their subjects as meaningful as this one. (E 30)
	Limitations of online gamification	5 from 63, 7.9%	I have missed the face-to-face classes, being able to interact better with the teacher and my classmates. (E 51) On some occasions I would have preferred individually, but it is true that in a group we have been able to help each other. (E 34)
