Ok, I must admit: when I saw what the game was about, I jumped right into it. (Yes, I'm a mecha enthusiast.)
To be fair, it was a real struggle at first, but after a second check to the tutorial, it was more clear. You did a great job at giving this feel of piloting a mecha and I liked it. On top of that, you gave your game an interesting finale. If you intend to keep on with the project, I wish you the best of luck. I'd be eager to see that.
The ONE thing I'd say as a negative thing is to not propose the player to check the tutorial again. I had to reset the game to look at it again because I didn't got it the first time.
Anyway, best of luck for the future!
EDIT: Oh something I forgot to mention, at one point the Enter key stops working for interactions. For me being used to the Enter key, it was very confusing to me, I thought I couldn't interact with anything at first. Was it on purpose?
