Very relaxing and fun! It took me a while before I figured out that the purple dudes were also enemies XD. I really enjoyed the atmosphere from the visual and aural aesthetic! When there wasn't another spawn I'd just stop moving and watch all my star babies floating around me :)
My only issue is it was hard to tell when my dash would kill enemies and when it was just recharging and I would die (it would be red for only an instant and you could still kill after it turned orange but not for long).
