Made it through to the end and it fits the theme really well! The involuntary aspect of throwing the potions and them having negative effects feels very unique to me and makes for a compelling game. I like the visual style of the game especially the thumbnail and the knight character. The lighting and background were good but the foreground scale feels a bit off (it feels like a tiny character running around on a desk or something).
The main menu music fits great and the in-game music sounded good to me, with the sound effects being even better. Also I like the integrated tutorial, but it would be nicer if each trigger area was a bit larger because I kept running straight through them and having to backtrack.
I found it quite difficult to dodge the knight's thrown swords, so maybe one could consider slowing them down a bit? The potion throwing mechanic worked nicely although it seemingly became easy to end up in a failure state were enemies keep duplicating faster than you can defeat them and the player is basically forced to retry the level. I was missing a bit of variety in the later levels but I know that you only had one week to work on the game.
All in all a very nice effort, I enjoyed it!
