I agree with PatrickZochAlves. There is a beginning of a great game here. The ship movement felt stiff, not very ship like. I had a hard time actually getting to the collectables after destroying the asteroid. I think maybe a radius collection or something like a tractor beam that pulled them in if you get close enough to the them would be nice. It could lock on to one at a time etc.. Introducing something that is antagonistic to the player would be a good feature as well. An alien that occasionally showed up and harasses you, asteroid that explodes and causes damage when it loses all its health. I think you have something to work with and that this can become something great. Keep up the good work.
