So yeah this is a really cool idea but the implementation particularly with the controls and user interaction is just frustrating.
It's bad enough to type in move commands, but you can't even press Enter to submit them. Also, make the commands themselves clickable instead of having to type them. I think you could even get away with the user user being able to directly press the commands like arrow keys, etc on the keyboard as well. I understand you want it paced a certain way also to allow for thinking, etc but it is just frustrating right now. I got past the first level but the type then click loop is just annoying.
You should also allow full screen for your game also because the default window is fairly small.
