thanks for the feedback! Nice to hear that people seem to like it! :D Yes, touchscreen implementation is on the list. It was what first came to mind when I brainstormed the game.
You’re right about the smaller asteroids, the give a smaller acore but dock a full amount of time and it doesn’t seem quite fair. So I’ll work on that in the next update. I’ll also be doing some general tweaks to the levels as well when I work on adding new ones.
