The tutorials when you do a new action is a good idea but I think it could have worked better if it happened at the starting point. For example when the game began I didn't have a point of reference as to what an asteroid looked like, I did understand as soon as I saw one but before that I had been navigating through empty space unsure as to what I was looking for, also how you lost asteroids once you changed to the white hole form.
Other than that I thought the instructions when you performed new actions were well explained.
