Nice small game! I love the nice, simple artstyle and the fog of war effect! Impressed you managed to fit everything in one screen too! I couldn't find the high-jump ability, so I used teleport to pretty easily wallclip and get acid-proof armour. After that I got rocket boots, and then just got yeeted up to the boss without any explanation. I personally could not figure out the boss's patterns at all, but a few attempts after I beat it, not exactly understanding how I did. A bit confusing, but great game overall!
