The controls are horrible, it's not clear what you need to do and it's not balanced at all. Once you get to multiple enemies who are able to shoot at you from all direction while you cannot even move, it's a problem. Also you cannot make traps, as you can only have two holes at once.
HOWEVER! There is a lot of potential in the concept. If it hard a wasd or arrow control set, pickups like shields and health, a clear tutorial and upgrades, it would be a lot better.
