Wow, what an amazing game.
Gameplay feels so good and so juicyyy I love it. The game is challenging but not too punitive.
Graphics and audio are great. Using stereo to tell the player where the enemy is is such a clever idea!
And the intro/cutscenes add so much you really nailed storytelling.
10/10 game for me.
(I also found the green heart easter egg, it made me so powerful I destroyed the last heart with it xD)
