This game is very fun due to the various pickables and means to destroy asteroids. I really liked the gameplay. Black hole was my favourite, cool mechanics.
A lot of room for improvement trough:
- Music and sound (obvious, but of least importance to me)
- Public high scores or some benchmark achievements to give players a goal.
- Misleading game name (there is no clicking)
- Hide the windows cursor.
- Art could be better
Technically the game is not really worth 3.5 stars, but I think it is fun enough to overlook many technical shortcomings, because fun is main thing in games and this one has it. It's still worth improving in next version.
