It’s been quite a while I didn’t talk about the progress of multiplayer, and in fact, I didn’t work on the multiplayer since the 0.4.0 update 3 days ago.
Now, I just finished implementing the base attack to it (common to everyone) without any “real” bug during testing (that affects gameplay and what happens).
During the test, I happened to remark a new bug I never saw before and that affects a core part of the gameplay: moving left and right. I am currently investigating the issue to find where it comes from.
An update will follow up soon after I fixed this

As for the big problem, it’s as such: the game doesn’t start and I don’t know or how much time it didn’t.
As I am using the game engine’s preview that doesn’t have this problem, I wasn’t aware of it…
