Very nice, it feels very polished, even has a tutorial.
The lighting system looks great!
It's a pretty fun mechanic to have to shake the potion, especially when you have a ton of enemies chasing you, nice tension ^^
Nice variety of potions.
It's very hard, I managed to beat the level but by rushing like crazy and having 50+ enemies chasing me by the end
Solid game, good job :)
(I also got the disappearing text bug)
