I recently made some larger changes to KoS, and one of the things I did was attempt to make Air into a playable game mode. I'm pretty happy with the results, and I'd like to share with you guys.
Air 2 is a game mode that could only exist in KoS. The premise is that you receive 'invisible' garbage -- that is, your stack gets pushed up, but nothing is below it. This makes for some interesting moves and strategies, but more than that it encourages playing for perfect clears. This is something you don't usually get to do in a competitive way!
In order to make games last long enough for this to be a viable strategy, I've significantly changed the garbage table for this mode. Spins, combos, and perfect clears are all detected the same as ever, but the amount they send is quite different:
* Spins send +1 per line * B2B sends +1 * Mini sends -1 * Combos send a flat +1 from 1-combo up * Perfect clears send +4
In most KoS modes, perfect clears are exclusive, meaning that they don't stack with other garbage. That is not the case in Air 2, and that's why the add from a PC is so low. You'll see that a good turn can send 10+ garbage even so!
The original Air mode was pretty much a garbage race. You could get lucky PCs, but garbage was too heavy to actually try f or them consistently. After playing this game though, it's obvious to me that it will be pretty hard to win without stacking some intentional spikes. I think there's lots of strategy left to explore, and this'll definitely stick around as a uniquely KoS feature
