Hello,
I don't have windows, and the export doesn't work with wine. So I couldn't play your game, sorry.
Two advices as you wrote it's your first game:
I see you used Unity. Next time, export your game in HTML5/WebGL, it's really easy with Unity, and more people will play your game (also, because of virus, many people will not event try to dl a game).
You used letters QWER for the game. French speaking people, Russians, Ukrainian, etc, don't use QWERTY keyboard. However, you don't have to map your game to all keyboard. Just be sure in the setting of you project to link actions with the physical position of the keys (everyone, knows where QWERTY should be) and not only to the letters themselves.
Good luck!
