Thank you for your very detailed feedback!
I planned at first to do weekly updates, but didn't expect that many feedbacks, so I'm taking a bit more time to do a "big" v0.2. It should be out this monday or tuesday.
All your points are valid, some will be included in 0.2 (feather gain, town feeling useless right now, super short runs being better by far).
For the browser issues, I will try to improve the experience if I find ways to counter the throttling. I won't spend too much time on it though, the web release is more for convenience (easy to deploy on my side, easy to play on yours). The goal is to have the 1.0 as a desktop app, or even before.
