Rating based off of the categories for this jam. Hopefully this provides useful feedback!
Fun 2/5: I can absolutely see what the intent of this was, and I like the idea, though I found the difficulty to be a bit too much for me. It was also a little difficult to tell where I was supposed to reflect the shots to, and the enemy AI was a bit erratic as a previous comment said.
Graphics 4/5: Very nice looking, I like the art style though I think making certain things stand out a bit more (like where to reflect shots) would really improve things.
Music/Sound Design 4/5: Nothing groundbreaking, but definitely satisfying, and non-intrusive. I think it lacks a little bit in the sound design side of things. It could do with a few extra sound effects for things like the door opening (I don't remember if there was one off the top of my head, because I only got it to open once and promptly died). But overall, it does the job well.
Concept 4/5: Definitely want to see something like this polished up a little more, perhaps made with a bit more of a friendlier difficulty curve for folks who haven't played games like this. Difficulty is a very common issue with games in this jam, my own included.
Very nice looking game, it's awesome you got this done in two weeks!
