I've found this game quite interesting, the mechanics are easy enough to grasp and can make quite a bit of fan.
Graphics are very prototype-y but I think they work very well and kinda add to the atmosphere of the game, really liked the evil red eyes in the background.
Now as for points of improvement I would have have for this game:
- Please add an outline to the UI counter for remaining enemies in the level, currently it becomes unreadable as it blends in with the light from the red glowy eyes in the background, which is a shame because it is very handy in later levels.
- It is cool that you tried to add some narrative, but I think you could have used that time to polish some other elements in this game; narrative is far from necessary in a game, and in this case it felt like clutter I had to skip through before I could get to the gameplay.
- Generally I feel this game could use for a bit more of player feedback; it is kinda hard to tell most of the time what happens when you attack an enemy, I think some particles, sound effects, and maybe camera shake could improve that
