Wow, this game was a blast to play. I love how intense the game got as you progressed through the level, as it added to the sense of dread as I was trying to collect the blood. However, it did start to feel a tad old collecting the same items as I was progressing. I think if there were some more items thrown into the mix, such as a shield power up, it can help to add another layer of challenge and reward on top of the compelling enemy design. Aside from this, great work!
