Indeed some places in the game got real laggy on my PC ^^' I got stuck at the gate of a castle, the only other way seemed to be bugged and I could not get through :(
The game feels alright but everything is a bit off... Not much impact when taking damage, the enemies' attack animations are not very clear, grabbing coins does not make any sound (it would be satisfying as there's a lot of them haha).
It need a bit more polish I believe, but nice work overall :)
