The level of polish here looks like a commercial release - I'm very impressed!

Interesting twist to the formula that requires the player to use a bit of thinking and timing for which color to set for the ball. At first I only looked at the controls to see if I could figure out the game mechanics and it was possible to figure out what to do by myself that way. I got to level 6.

With the black orbs I'd prefer if these were a bit more visible because they sometimes surprised me. Also level 3 took quite a while with the narrow part of the middle virus. With level 6 the ball would take a while to get past the past, slowing down the gameplay. In other levels when the ball would bounce horizontally it would eventually get interrupted on its own by the floating obstacles, which was nice.

Nice game overall.

I had a lot of fun playing this. I think it would've been great if your music played quietly during the main game or different music played during that time.  I still enjoyed it a lot! Good job!
