Great concept. Mobile game would be better than windows. Had me getting hooked to it until the level got too hard. Suggest more to the leveling system so that if you suck you can still just build your power till you kill it. Player shield is also OP, since not every hit connects  and breaks part of it. Suggest raid dives go through player shield and cause the player to destroy their own shield if they fire at it.
Good work.
PS, I discovered this on the itch.io Youtube channel.
