The game is quite interesting. I love the graphics and concept of it, but I am not 100% sure if removing the player agency of attacking is a good move in such games. I mean, there is not a lot to do when you can only move. If you really want to do movement only, you would probably need more movement options and upgrades just to make it more engaging. But anyway, I think you are onto something quite nice, and it definitely deserves a lot of praise on that. Good job!
