The moment I saw the page layout I thought: wow I never would've thought of that! The visuals are obviously very impressive, especially the fact that you managed to make 45-degree rotation work well. You've given me a lot of ideas to think about!
The only nitpick I have about the game is that the enemies are too repetitive. Otherwise the level design was pretty good. I liked the fact that you can just commit suicide in the water dungeon to get back to the door faster lol. Also I guess the holes are for the same purpose right? So after you get a key you don't have to manually walk back, ha!
