This game is really great, there are so many details. A creative theme, nice music, lore, fun gameplay, a clear goal, different enemy types, I could go on. I mean, what games have the player moving constantly moving forward, but killing enemies from BEHIND?!
Now with the praises aside this game obviously has its flaws. The art being the main one. With such basic graphics, all you'd need is different lore and this game could be anything else. There could've been ANYTHING to represent vampires visually, but it's all basic shapes.
Second the gameplay, while pretty fun, is really fast and the controls are clunky. I found my best strategy to be simply go in circles and occasionally replenish blood in the sea when I went below 20 blood. Very boring as you might imagine.
Additionally, the UI being basic text makes it hard to read. Plus the fact that it updates slowly makes it even harder to read how much blood I have left. At the very least add a color change or animation when blood is getting too low or high.
Overall, I think the game has a lot of potential and if it didn't have the few flaws I mentioned, it could very well win the competition
