I really liked this one. The particle effect when the balls hit is actually awesome.
I think it has a lot of potentially as well if you wanted to flesh it out. Like maybe adding a few more mechanics, trying to hit blocks in the middle of the swap or something.
How did you do the level? Random, or a predetermined series?
Thanks, I had fun with this one. I think it has potential.
The level is randomly generated but I made a helper function for the spawner.
I used Vectors (X, Y) because it's an easy way to expose two linked float values to the editor.
X is spawn frequency in seconds, Y is how long that 'phase' is active.
All the code is on GitHub, too. https://github.com/Falconerd/30-games-30-days/
