Nice game, plays quite well and the mechanics are well implemented. Interesting choice of palette, I would have gone colorfull though, and good SFX. Spritework, maybe sprites are a bit too big for the resolution leaving a small playing area. You also went over the restrictions with the text boxes not complying to 64x64. Got killed but I had no idea about my health level or being hit at any point, so a bit more feedback to the player would be quite necessary.
