No problem!! I've really found that playtest videos are king for proper feedback, you really start to see what ideas get clearly communicated to your player and what don't. (I've watched many videos of people playing my game, getting caught in a weird spot, and feeling so frustrated that I can't reach out and explain it to them lol).
I think you've got a solid base and would love to play it again with healing etc. Remember that I also don't play this genre of game much, so others probably could have picked up C to heal. You need noob feedback like mine and expert feedback lol.
