Thanks for the comments everyone.
@TummyFish, insightful comment. Thanks.
Everyone else, I'm working on reducing the lag. I'll post here once it's been updated with a fix. It should fix the lag, and therefore the controls.
Thanks ExtremePopcorn. You're absolutely right. This isn't revolutionary, at all. I was merely trying to make a solid multiplayer snake game, at first. This is my first multiplayer game, so I'm glad I didn't start with something more complicated.
I'm not expecting loads of attention with this. Just hope people enjoy it.
There is statistics list, though. You have to register on nonoba.com, and on the game page there's statistics for various things you do in the game. I plan to add more when I've gotten the game a bit more stable on the basic side of things.
I'm still in the process of learning how all this multiplayer thing works, so this is early stages stuff. Not that that matters, but I still wanted to get it out so that I could get feedback like yours. They help a lot.
Thanks greg, Jamcob, saaaam and Icaterus.
Saaaam, I'll look into that. It seems these glitches have to do with bad collision detection on the moving blocks.
greg, you're not alone! Believe me. I do that car scenery thing all the time. Glad you liked the game!
