i really like the game. maybe it's my old notebook (from like 2015or so) but when there is like more than 2 or 3 enemies present on the map, stuff slows down signifactly. i move like in bullet time. once all enemies are dead (and likely particles are way fewer) then it runs normal.
so yea, bit of performance issue.
but nice game, jsut feells slow with multiple enemies that way
