holy crap this game was hard. but i loved every second of it. I like the metroidvania aspect of the game. the graphics where also really beautiful.
one thing : sometimes after i died the fire instantly flew in the direction of my curser because i was holding the left mouse key to dash. this resulted in a few cheap deaths , sometimes even three or four times in a row. Maybe you could add a timer that prevents you from instantly jumping after respawning . this would fix the issue.
otherwise a very good game , my favourite so far.
