I have been unable to replicate the problem but I got to around level 12 in survival then switched to speed. the correct number of balls came out but the text said like level 13, 14, and 15 every for balls.
tip to make more realistic and slightly easier. In physics a ball wont fall unless more than half of its mass is hanging off the edge, rather than just touching the edge. you can go about this however you want but what comes to mind is an invisible or hidden layer that checks collision that is exactly the current boundaries plus the radius of the ball.
way too slow of movements, each building is 2 levels? after the first building all buildings are at the top. I dont like only vertical movement. Background doesn't loop. Collision detection doesn't work. The are no boundaries...
a little too easy once you get the hang of it you can sit near the top and survive virtually forever. I like the uniqueness. Got a little boring not shooting and just avoiding. Also the ship movement graphics are too choppy.
liked the healthbar on the ship... sort of. I liked the creativity putting it there, but was a little to narrow to read easily. other than that to make it more challenging just have them shoot more often or have them come in more often. to lose I had to kill myself.
