RG,
I think it looks really good. Great casual game.
Mechanics are smooth and intuitive.
It is very addicting. I kept wanting to try again, again, again.
I had to make my self stop before my eyes exploded from staring at the screen so long.
I agree with Graham’s gameplay bullet points 1,2, & 4
I am sure he is right about the others as well, I only emphasis 1,2 & 4 because I had those same exact thoughts as I played it last night, and I do think those 3 points are key. And I think those can be easily added to the game by someone with your skills.
Until I can play it further and get to higher levels, at this point I just had one thought to add:
Maybe those ‘gold stars’ or gold rings, that Graham mentioned could be an incentive for player to accumulate 10 of them. And once accumulated, player benefits from an immediate positive effect. Maybe player has invincibility for 20 seconds, so player does not die when smashing into reds or the walls for that period of time. So in addition to the ‘achievement’ player enjoys while collecting stars, the player also enjoys a ‘reward’ right with in the game environment, once player has collected 10 stars our whatever number you set.
Best of luck!
Bob
