Last week end was a blast, the demo got popular on twitter and reddit. Thanks a ton to everybody who played the game, and especially to those who took the time to provide feedback. So here are fixes for 3 issues that got mentioned:

Board Look

The previous textures used for the board were too contrasted. This was a bit distracting and made the board not as easy to read as it could be. So I looked at this again, tested with several new textures, tweaked some colors and we now have something that is a bit more muted, while still preserving the wood look. You can see in this screenshot the previous one on the left, and the new one on the right.

More Obvious Tutorial

Many players were eager to start playing when opening up the game, and skipped the tutorial. Honestly, I completely understand, I often do the same. But some skipped it so fast they didn't realise there was a tutorial at all. So I've added a more prominent button, to at least let you know that there is one, and that it may be useful to read it through. This way, you can at least start it when you want.
Although this doesn't change the fact that tutorials are pretty boring. Ideally there would be no need for one. Or at the very least, information would be slow dripped to the players without interrupting the flow. But since here you need to know how each piece can move from the start, it still feels like a dedicated tutorial is hard to avoid. We'll see, maybe there is a better way, I'm still thinking about it.

Castling Rule Fix

In chess, there are a bunch of criteria on wikipedia that defines if castling is allowed or not. When I implemented this move, I looked those criteria up to be extra sure of what I had to put in code. And I looked them up again. And again. And then I was pretty sure I got that right. But turns out I got overzealous and added a rule that did not exist! That invented rule was that you couldn't castle if you had been in check before. Thankfully a kind player pointed it out. So I removed that, and now you can properly castle following the official chess rules. That's it for now. There is more feedback I'm thinking about and which may or may not make it in the game. We shall soon see!
