Great game! This is a really fast paced game which doesn't overstay its welcome. I thought the echoes of the past related puzzle mechanics were a clever addition. This game hits all of the Metroidvania beats to a competent level. I only have a couple suggestions to improve the game. I suggest tuning because it was too high when dropping down to lower levels. I also suggest tuning the Final bosses' attacks, because there was there wasn't enough time to react and dodge them.
