Yes, you're invited to give it a try! Each game takes a few minutes only, and you can join or leave after every game.
I can't keep track of 8 players either. We try to focus on important parts and ignore all the unimportant areas. I miss a lot during play: I've In the last session, both Icho and Flopsy reported physics bug during voicechat, and I missed those completely. I saw them only on the recordings.
Lix with bad internet: Low bandwith is perfectly fine, the networking protocol relays only the assignments, no physics. If you have lag spikes, try and see: 1-3 seconds of lag is no problem. With 5-10 seconds of lag, the server might conclude that you have disconnected. Even if that happens, others can finish without problems, and you can reconnect for the next game.
Lix on old hardware: I don't know what will happen, it'll be good feedback for me. The physics will speed up to adjust for computation lag, that's usually no problem. Large maps can be resource-hungry because Lix savestates internally often. Crashes can happen, but even in the 3.5-hour session with 6-8 players, only 1 player crashed a single time for out of VRAM. Still, I take crashes seriously. In the long term, I want to optimize for less memory.
