Pretty good for a first game
It's too simple to be great, but everyone have to start somewhere. Mouse control had very good response. Unfortunately I didn't get to test the 2 player version, however, I think keyboard controls are going to be really tough considering the speed those rocks were coming down after 60 seconds.
All in all, a solid take on an overused theme. Keep up the good work. let's see what you're showing us next week then.
