Thanks for your great feedback, it was really helpful knowing what was exactly the issues in my game and I appreciate how you managed to explain them so well.
For the Attack/Move thing, I really REALLY like your idea of making them the same thing, I envisioned at first that the game would have a lot more skills than it has at the moment, some of which have different effects depending on wether you're attacking or just moving, but I didn't manage my time very well so I ended up with only 4 skills.
In case of the health bar, I made it purely to make the king a more valuable piece, in the future I think of making a skill called "Regular chess" that makes all pieces have 1 HP ;).
Pawns reaching the end is a BAD overlook on my part, I'm sorry.
The tile destroyer not working is a bug I encountered and I'm not sure if I actually fixed it entirely, also the water tile idea is pretty good, thank you for it.
The AI is honestly so bad, the first 3 stages it just doing things randomly, and in the later stages it just gets agressive and tries to prioritize attacking over winning, I'll have to work on that more.
Thanks a lot for your review of the game and for the discord server, I couldn't find it anywehre, so if you can please send me the link for it.
