I'll do my best to not repeat what others have said.
First, the technical stuff:
Technical stuff:
- The timer should start when we first place the door. I think it's rather unfair to not give us time to read the tutorial.
- With physics, Rapier could help a bit, but, just installing and hoping for the best won't be enough. You could solve most of them by fine-tuning the numbers; for example, you could limit the speed of the ball, which will keep it from going to crazy, or clamp the angle of reflections to prevent the ball from getting stuck.
- The sound seems to cut off whenever we finish a level; that can get annoying really quick.
Moving on to design:
The design:
I don't have many notes in this regard, but there's one thing that caught my attention -- that damn door.
Well, I know you said in your video to not tell you why you shouldn't keep it, so I won't. Instead, I'll say this, you should double down on this type of craziness; you call your game "Unruly", therefore things don't have to make sense. Personally, I'd make the ball break the door on contact because that would be a bit funny.
Where to publish it
You don't have to choose, there's no exclusivity deal and the more places you publish your game, the more eyes you'll get. With that said -- if you only want to choose one, Steam is the best option.
Good luck on your journey! ＼(-_- )
