Cool game! I really liked the pixel graphics. The explosions looked really nice. The camera shake was also a nice touch. At first I had some trouble finding the difference between the enemies, projectiles and hearts so I would suggest making them different colours. I wouldnt say that the game mechanics are very creative as I have seen many top down survival type shooters in this game jam so far. To make the game stand out it would have been nice if you added some sort of chaotic twist. But overall I think its a pretty enjoyable game. Nice job
