Walking with WASD, shooting with the mouse and placing the castle with F felt natural, and the dotted build zone made it clear where things could go. What confused me was the greyed-out Battle button. Pressing B only said "build your castle first", and I could not tell the castle was already under construction, because its progress counter is tiny and sits near the top edge. Show the build progress on the castle itself, and put the reason on the Battle button, for example "castle ready in 20 s".

First of all, thank you so much for playing and for taking the time to share your feedback!
I'm currently making several structural improvements to the game, and comments like yours are helping me a lot to polish the experience before the official release.
I'm working towards publishing the game on the Google Play Store within the next week. This will be my very first game published there, so it's a pretty special milestone for me!
Google requires at least 14 testers to participate in a 14-day closed testing period before the game can be released. I'd be really grateful if you could join the testing group!
I'll let you know as soon as the updated version is ready. Thanks again for helping me make this game better!
