Thanks so much, I'm extremely happy to hear that about Sunken Fear as it was definitely the most time-consuming one to make!
My main regrets are some silly issues like getting stuck in some places, but also I semi-wished we could have given the option to use tank controls as it is the main scheme that I have experience with, but I feel that most people don't like them - so we ended up with the relative controls we have now but they are a bit jankier than they could be.
