I like the overall vibe (and the music adds a ton here!). More in-game hints regarding the controls would have been nice: I had to look up the action button (dunno why, but I expected 'E', not 'F'), accidentally quit the game once (since I expected escape to pause the game), then struggled tremendously with moving from the first moving platform to the second (still not sure if one can double jump or have to abuse coyote-time there) and even after finishing the game I don't quite understand how the flight mode works (felt like looking up makes one fly a lot farther?!). Don't want that to come across overly negative, though: I enjoyed your game enough to finish it, after all. Good job! :)

Took me waaay too long to figure out I could double-jump and then similarly with activating the vampirism. Eventually I read the page and figured it out. Would be nice to have more in-game hints for that sort of thing though.

I was also surprised that (at least on Linux) pressing escape quit the game, which was a bit frustrating because it meant I lost my progress. I kind of wish it wasn’t timed, or at least that the time left was more obvious.

Regardless, I liked the idea of the drinks unlocking additional vampiric powers, and as a result getting stronger as you go. Nice work!
