I tried your game in browser (Firefox/Windows) and unfortunately found some significant hurdles.
- UI does not scale when playing in small window, cutting off part of the screen
- UI does not scale in full-screen either, making use only of small part of the screen
- Game does not capture mouse, making it almost unplayable for me (since I have browser gestures enabled). If you do not want to capture mouse for some reason, I recommend to add keyboard controls.
- Controls in “Options” and “How to play” screens do not react to input, including “close” button, forcing player to restart game
- The gameplay does not resemble the video you posted, towers seem to be located inside the walls (?) and are invisible to player.
So it seems that the game needs some work. I can test again if/when these problems are fixed.
