The movement definitely needs improvement, and the controls were a giaant oversight lol, I like using my keyboard like a big controller but I have learned that's not a shared sentiment.
I'm a bit curious to know when the dash doesn't trigger. Few key things I wasn't able to teach was that below 15 seconds you can no longer dash, and the dash depends on the direction you are moving (hold W to dash upwards). If it isn't working outside of these conditions, that's something I would definitely like to look into
