Couple comments, since we can warp at walls, we either need an indicate an enemy is there or something else. Lot of times i'll be going to warp and an enemy will spawn on my head while i'm halfway through.
If we're using our mouse to aim and shoot, probably need to give us more than the 4 cardinal directions to shoot, especially since both us and the enemy can move in diagonal and more flui motion.
Seems to be an alpha concept based on how much there is here. Curios to see what else you'll add or do to the game. I'll be able to give more constructive feedback with more content to see where you're trying to take the game's direction. Right now, it's not super clear.
