I got captivated by the picture of your game, from the first time I saw it I knew what art-style it was going to be hehehe 😄
The game's atmosphere is quite good, I like how everything is black and white except the player and the abilities, and the graphics remind me of those of the PSX in a really good way, you nailed making a classic feeling game, congratulations! 😁
The gameplay aspect is a little bit more lacking, as it lacks depth in the combat mechanics. I understand that this is a jam project, but I'd have used more development time toward the battle mechanics. Also, I'd make some more visual indications when damaging an enemy, as right now I felt they were damage sponges.
Other than that, the setting is interesting and the game has charm to it, keep working on it! 😃
