I really liked this game! It fits the theme of "death is an opportunity" in the way that you can use the guards (and king!) that you killed to solve puzzles and vault obstacles with! I also really like the colors and aesthetic in the game, it kinda reminds me of terraria. I liked the small challenge that the king boss fight brought at the end, and I loved that the game was short, sweet, and to the point!
Speaking of points, I also liked the spikes! They look a lot like the ones from I Wanna Be The Guy and I'm a big fan of those rage platformers like Super Meat Boy.
Great game, I really liked it!
