I have a short interview next week at a small videogame company for a programmer position. They are currently working on a new game, so I downloaded the demo and played through it. There are some bugs and a few objectively bad design choices. For example, enemies' names are displayed above them in black text, so when they are over a black background their names are rendered invisible.
I took screenshots of the errors I found (around 10). Should I comment them to my interviewer? I intend on explaining how I could solve the problems, so as to show I know about game design and software, and that I took the time to know their game and analyze it for improvements. I am also going to apologize in advance since maybe they have already solved them. But maybe it is seen as just criticizing and my comments end up having a negative impact. What should I do? The main creator of the game is not the interviewer by the way.
Edit 1: thanks everyone for your input, it has been very helpful. After the interview I'll comment how it went, so as to help others who stumble upon this question.
Edit 2: I had the interview, and it went great. Having read the comments here about how negative it could be to bring up the bugs and point out some design choices, I decided the best would be not to say a word (unless the interviewer wanted me to share my thoughts about the demo, and comment if there was something wrong about it or that could be improved). The interview was more focused about what my skills are, what would I want to do at the company, my studies, and my personality. Had the subject about the demo been brought up, the best approach would have been, like @Old_Lamplighter said, to rephrase any comments in a more positive way, while pointing out the good things. Thanks everyone for your help.
