The floating issue I mentioned is probably that Sonic throw then.
And don't worry I think Demo Day is meant to be Debug Day to some degree too. When you have been working on something too much you tend to oversee things but others won't, that's why others feedback is so helpful.
I'm not sure if tumblr has an actual character limit, but I have written pretty long entries there. You can also keep a devlog for each game here on itch, but for a more general, or talking about various projects tumblr is probably a better option.
Again, great job, and I'm glad I can be helpful!
