No worries! I love interacting with other indie game enthusiasts; it gets boring sitting behind a desk developing games without interacting with the indie game community.
I wouldn't worry too much about it. It seems like your intentions are good; as long as you reflect that in your words, you should do fine.
What helps me criticize others well is focusing all your criticism on the game (NEVER target the developers) and try to end on a positive note (such as bringing out a call to action or even counterbalancing it with something that impressed you).
Please share your YouTube channel with me! I'd love to give you a subscribe and support what you're doing. :D
