The player speed felt really nice to me. I'm not a patient individual in platformers so I'm always a fan when a developer leans more towards maybe going to fast rather than maybe going a little slower. I'm also a big sucker for mobility in games as well so a dash>jump>dash>jump>dash chain felt immensely satisfying.
The level design felt a little simple, but your player controller felt excellent and balanced it out so that it was satisfying even with simple obstacles like a wider than usual pitfall. Well done!
