1600+ as POC.
Randomness, random, rand()...
Probably I'll skip this one. No time to tweak.
Tip: Put few independant anchor points, which will be used to create catcher in your next level. In this one (in previous "Smile" level also) ANY change - changes everything. What for? For "Luckiest will win."?
P.S. Level IS good. I just grumble.
Feel the Power of the Dark Side.
