- Nice music on the title screen, but while taking the time to read "about" and "controls", it stopped: maybe make it loop
- some of the tiniest text was difficult to read
- after reading the optional about section, the wall of text after clicking on "start" felt a bit overwhelming: maybe feed it to the player in smaller chunks
- cute sound effects
- the auto aim for left-click attacks made combat very easy
- also, while left-click had auto-aim, right-click went in player facing direction: I would've expected it to go in mouse cursor direction
- not sure how right-click attacks work, the mist around the player took ages to appear, but then twice in quick succession... idk what triggers an "allergic reaction"
- the boss can be trapped behind a wall, making it a very simple fight
- the enemies moving away after they hit you was a nice mechanic to give a moment to catch yourself
- took a while to understand that potions make me faster for a short time
